Abstract
BACKGROUND Isolated limb perfusion (ILP) is a regional cancer treatment in which high-dose chemotherapy is administered in an isolated extremity. The main side effect is regional toxicity, which occasionally leads to nerve damage. Measuring neuroaxonal biomarkers, might be a method predicting such complications. Therefore, the primary aim of the study is to investigate if neuronal biomarkers are measurable and alters in an isolated extremity during ILP. Secondly, if postoperative regional toxicity, alterations in sensitivity, and/or muscle strength are correlated to the biomarker levels. METHODS Eighteen scheduled ILP-patients were included in the study. Glial fibrillary acidic protein (GFAP), neurofilament light (NfL), and tau concentrations were measured in plasma sampled preoperatively, at the start and end of the ILP, on days 3 and 30, using ultrasensitive Single molecule array (Simoa) technology. The patients were assessed by a physiotherapist pre- and postoperatively. RESULTS At ILP end, significantly higher NfL and tau levels were measured in the extremity than in the corresponding systemic circulation (NfL; 17 vs 6 ng/L, p < .01, tau; 1.8 vs 0.6 ng/L, p < .01), and the extremity levels were significantly increased at ILP end (NfL; 66 ± 37%, p < .001, tau; 75 ± 45%, p = .001). On days 3 and 30, significantly increased NfL and GFAP levels were measured systemically (NfL day 3: 69 ± 30%, p < .001; day 30: 76 ± 26%, p < .001; GFAP day 3: 33 ± 22%, p < .002; day 30: 33 ± 23%, p ≤ .004). Finally, no significant correlations were found between regional toxicity or between postoperative muscle or sensitivity decrease and biomarker release. CONCLUSION During ILP, NfL and tau levels increased significantly. No obvious correlations were observed between biomarker release and regional toxicity or decreased muscle strength or sensitivity, although large-scale studies are warranted.

Abstract
Isolated limb perfusion (ILP) is widely accepted as treatment for recurrent melanoma limited to the limbs. The use of ILP has decreased in recent years with the introduction of potentially effective new systemic therapies. We evaluated retrospectively if ILP still may be a treatment option in locally advanced melanoma. In Finland, ILP is centralized to the Comprehensive Cancer Center of Helsinki University Hospital. We included all ILP patients treated at our hospital between 2007 and 2018. Clinical factors and treatment outcomes were retrospectively evaluated. Altogether 60 patients received ILP. Toxicity was mostly transient. The overall response rate was 77% with 35% complete responses and 42% partial responses. The median progression-free survival (PFS) was 6.1 months (range 0.6-116.5 months) and the median melanoma-specific survival (MSS) was 29.9 months (range 3.5-138.7 months). Patients with CR had superior median PFS (19.7 months, range 2.5-116.5 vs. 4.5 months, range 0.6-39.7 months, P = 0.00003) and median MSS (median MSS not reached vs. 25.9 months, range 3.5-98.7 months, P = 0.0005) compared to other responders. Younger patients (<69 years) had longer median MSS (47.2 months, range 3.5-138.7 vs. 25.9 months, range 8.4-125.4 months, P = 0.015) compared to patients over 69 years. Treatment outcomes of Finnish ILP patients were comparable to earlier studies and some long-term survivors were observed in the group of complete responders. Median PFS and OS were longer for patients achieving a CR. Treatment was well-tolerated also among older patients.

Talimogene Laherparepvec (T-VEC): An Intralesional Cancer Immunotherapy for Advanced Melanoma. Cancers (Basel) 2021; 13:cancers13061383.

Abstract
Simple Summary Talimogene laherparepvec (T-VEC; IMLYGIC®, Amgen Inc.) is the first oncolytic viral immunotherapy to be approved for the local treatment of unresectable metastatic stage IIIB/C–IVM1a melanoma. Its direct intratumoral injection aim to trigger local and systemic immunologic responses leading to tumor cell lysis, followed by release of tumor-derived antigens and subsequent activation of tumor-specific effector T-cells. Its approval has fueled the interest to study its possible sinergy with other immunotherapeutics in preclinical models as well as in clinical contextes. In fact, it has been shown that intratumoral administration of this immunostimulatory agent successfully synergizes with immune checkpoint inhibitors. The objectives of this review are to resume the current state of the art of T-VEC treatment when used in monotherapy or in combination with immune checkpoint inhibitors, describing the strong rationale of its development, the adverse events of interest and the clinical outcome in selected patient’s populations. Abstract Direct intralesional injection of specific or even generic agents, has been proposed over the years as cancer immunotherapy, in order to treat cutaneous or subcutaneous metastasis. Such treatments usually induce an effective control of disease in injected lesions, but only occasionally were able to demonstrate a systemic abscopal effect on distant metastases. The usual availability of tissue for basic and translational research is a plus in utilizing this approach, which has been used in primis for the treatment of locally advanced melanoma. Melanoma is an immunogenic tumor that could often spread superficially causing in-transit metastasis and involving draining lymph nodes, being an interesting model to study new drugs with different modality of administration from normal available routes. Talimogene laherperepvec (T-VEC) is an injectable modified oncolytic herpes virus being developed for intratumoral injection, that produces granulocyte-macrophage colony-stimulating factor (GM-CSF) and enhances local and systemic antitumor immune responses. After infection, selected viral replication happens in tumor cells leading to tumor cell lysis and activating a specific T-cell driven immune response. For this reason, a probable synergistic effect with immune checkpoints inhibition have been described. Pre-clinical studies in melanoma confirmed that T-VEC preferentially infects melanoma cells and exerts its antitumor activity through directly mediating cell death and by augmenting local and even distant immune responses. T-VEC has been assessed in monotherapy in Phase II and III clinical trials demonstrating a tolerable side-effect profile, a promising efficacy in both injected and uninjected lesions, but a mild effect at a systemic level. In fact, despite improved local disease control and a trend toward superior overall survival in respect to the comparator GM-CSF (which was injected subcutaneously daily for two weeks), responses as a single agent therapy have been uncommon in patients with visceral metastases. For this reason, T-VEC is currently being evaluated in combinations with other immune checkpoint inhibitors such as ipilimumab and pembrolizumab, with interesting confirmation of activity even systemically.

Abstract
Summary
Background: The treatment of malignant melanoma or sarcomas on a limb using extremity perfusion with tumour necrosis factor (TNF-α) and melphalan can result in a high degree of systemic toxicity if there is any leakage from the isolated blood territory of the limb into the systemic vascular territory. Leakage is currently controlled by using radiotracers and heavy external probes in a procedure that requires continuous manual calculations. The aim of this work was to develop a light, easily transportable system to monitor limb perfusion leakage by controlling systemic blood pool radioactivity with a portable gamma camera adapted for intraoperative use as an external probe, and to initiate its application in the treatment of MM patients. Methods: A special collimator was built for maximal sensitivity. Software for acquisition and data processing in real time was developed. After testing the adequacy of the system, it was used to monitor limb perfusion leakage in 16 patients with malignant melanoma to be treated with perfusion of TNF-α and melphalan. Results: The field of view of the detector system was 13.8 cm, which is appropriate for the monitoring, since the area to be controlled was the precordial zone. The sensitivity of the system was 257 cps/MBq. When the percentage of leakage reaches 10% the associated absolute error is ± 1%. After a mean follow-up period of 12 months, no patients have shown any significant or lasting side-effects. Partial or complete remission of lesions was seen in 9 out of 16 patients (56%) after HILP with TNF-α and melphalan. Conclusion: The detector system together with specially developed software provides a suitable automatic continuous monitoring system of any leakage that may occur during limb perfusion. This technique has been successfully implemented in patients for whom perfusion with TNF-α and melphalan has been indicated.

Abstract
BACKGROUND AND OBJECTIVE Response rates of cutaneous-subcutaneous or lymph node metastases of melanoma to systemic chemotherapy are rather low. We report our clinical experience with superficial and deep regional hyperthermia in combination with radiotherapy and/or chemotherapy with carboplatin. PATIENTS/METHODS We treated 15 patients with metastatic melanoma (6 men, 9 women; age 39-84 years, mean age 60 years) by using superficial or deep regional hyperthermia produced by electromagnetic energy. Superficial hyperthermia was delivered to skin or lymph node metastases in combination with radiochemotherapy in 12 patients, while deep regional hyperthermia was administered with an annular array applicator to lymph node metastases either in combination with radiochemotherapy (1 patient) or with carboplatin alone (2 patients). The clinical response was assessed by clinical evaluation and/or computer tomography and/or ultrasonography at monthly intervals. RESULTS Both superficial and deep regional hyperthermia was well tolerated. We observed 5 complete local remissions (34%), 6 partial local remissions (40%) and 2 patients with stable disease (13%). The best results were obtained in cutaneous or retroperitoneal metastases. CONCLUSIONS Local response can be achieved in inoperable metastatic melanoma using superficial or deep regional hyperthermia in combination with radiochemotherapy or chemotherapy.

Abstract
Melanoma often spreads to cutaneous or subcutaneous sites that are amenable to direct, intralesional injection. As such, developing effective injectable agents has been of considerable interest. Talimogene laherperepvec (T-VEC) is an injectable modified oncolytic herpes virus being developed for the treatment of advanced melanoma. Pre-clinical studies have shown that T-VEC preferentially infects melanoma cells and exerts antitumor activity through directly mediating cell death and by augmenting local and even distant immune responses. T-VEC has now been assessed in Phase II and III clinical trials and has demonstrated a tolerable side-effect profile and promising efficacy, showing an improved durable response rate and a trend toward superior overall survival compared to granulocyte-macrophage colony-stimulating factor. Despite these promising results, responses have been uncommon in patients with visceral metastases. T-VEC is currently being evaluated in combination with other immune therapies (ipilimumab and pembrolizumab) with early signs of activity. In this review, we discuss the preclinical rationale, the clinical experience, and future directions for T-VEC in advanced melanoma.

Abstract
INTRODUCTION The aim of the study is to evaluate the limb salvage rate achieved by treating locally advanced extremity sarcoma and melanoma by hyperthermic isolated limb perfusion with melphalan and TNF-α (ILP-MT). MATERIAL AND METHODS A retrospective study was conducted on patients suffering from locally advanced soft tissue sarcoma and melanoma of the limb and treated by means of ILP-MT between November 2001 and February 2010. The response rate, toxicity, complications, disease free intervals, overall survival and limb salvage rate were evaluated. RESULTS A total of 30 patients (19 females and 11 males) with a median age of 60 years (14-82) were treated by this technique. The overall response rate was 93.4% (complete, 46.7%; partial 46.7%); the mean follow-up was 23 months. The median duration of response was 5 months (0-62), The median overall survival was 13.5 months (range 1 - 62). Limb salvage rate was 86.7%. Eleven patients are currently alive (5 without disease, 2 with residual disease on treatment, 2 with local progression and 2 with systemic progression). CONCLUSION With the use of ILP-MT we have avoided the amputation of 26 limbs affected by locally advanced sarcoma or melanoma. ILP-MT is feasible and safe in a multidisciplinary environment.

Abstract
OBJECTIVE Isolated limb perfusion combined with melphalan is an accepted treatment for obtaining locoregional control in advanced melanoma of the extremities and other malignant neoplasias restricted to the limb. This study aims to examine the factors associated with toxicity caused by the regional method. We considered the technical aspects of severe complications associated with the procedure in an attempt to diminish the patient morbidity that occurs during the learning curve. METHODS We conducted a retrospective analysis of the records of patients who underwent perfusion at the AC Camargo Hospital in São Paulo, Brazil between January 2000 and January 2009. The Wieberdink scale was applied to classify local toxicity and its relation to clinical and laboratory variables. RESULTS Fifty-eight perfusions were performed in 55 patients. Most patients (86.2%) presented a toxicity level between I and III. Grade V toxicity was seen in five cases (8.6%), four of which occurred in the first 2 years. Creatine phosphokinase, an important predictive factor for toxicity, had an average value of 231.8 for toxicity grades I-III and 1286.2 for toxicity grades IV-V (p = 0.001). There was a relationship between the melphalan dose and toxicity, which was 77 mg (25 to 130 mg) for toxicity grades I-II and 93.5 mg (45 to 120 mg) for toxicity grades IV-V (p = 0.0204). CONCLUSION It is possible to prevent the toxicity associated with melphalan by adjusting the dose according to the patient's body weight (especially for women and obese patients) and the creatine phosphokinase values in the postoperative period.

Abstract
Background Approximately 5–8% of melanoma patients will develop in-transit metastases (IT-mets). Tumor necrosis factor-α (TNF) and melphalan-based isolated limb perfusion (TM-ILP) is an attractive treatment modality in melanoma patients with multiple IT-mets. This study reports on a 20 years experience and outlines the evolution and major changes since the introduction of TNF in ILP. Methods A total of 167 TM-ILPs were performed in 148 patients, between 1991 and 2009. TM-ILPs were performed at high doses of TNF (3–4 mg) from 1991 to 2004 (n = 99) and at low doses of TNF (1–2 mg) from 2004 to 2009 (n = 68) under mild hyperthermic conditions (38°C–39.5°C.). Melphalan doses were unchanged at 10–13 mg/l (leg and arm, respectively). Characteristics for the 167 ILPs were: 81 stage IIIB, 65 stage IIIC, and 21 stage IV disease. Results The overall response rate was 89% (n = 148). (Complete response [CR] = 61%; partial response [PR] = 28%). CR rates correlated with stage (P = .001) and with high-dose vs. low-dose TNF (70% vs. 49%; P < .006). High-dose TNF prolonged local control (median 16 months vs. 11 months; P = .076). Survival was not influenced by TNF dose. CR after ILP and number of lesions also correlated with local progression-free interval. Overall survival did correlate with stage of disease (P < .001), size of the lesions (P = .001), and a CR (P < .001). Conclusions This 2-decade single-center experience demonstrates that TM-ILP is a safe and effective treatment modality for melanoma patients with multiple IT-mets. Higher dose of TNF was associated with significantly higher CR rates and prolonged local control without an effect on overall survival.

Abstract
For in-transit melanoma confined to the extremities, regional chemotherapy in the form of hyperthermic isolated limb perfusion and isolated limb infusion are effective treatment modalities carrying superior response rates to current standard systemic therapy. Despite high response rates, most patients will eventually recur, supporting the role for novel research aimed at improving durable responses and minimizing toxicity. Although the standard cytotoxic agent for regional chemotherapy is melphalan, alternative agents such as temozolomide are currently being tested, with promising preliminary results. Current strategies for improving chemosensitivity to regional chemotherapy are aimed at overcoming classic resistance mechanisms such as drug metabolism and DNA repair, increasing drug delivery, inhibiting tumor-specific angiogenesis, and decreasing the apoptotic threshold of melanoma cells. Concurrent with development and testing of these agents, genomic profiling and biomolecular analysis of acquired tumor tissue may define patterns of tumor resistance and sensitivity from which personalized treatment may be tailored to optimize efficacy. In this article rational strategies for treatment of in-transit melanoma are outlined, with special emphasis on current translational and clinical research efforts.

Abstract
BACKGROUND The aims of the study were: (1) to determine toxicity, response rate, local-regional control, and survival in the entire population of the perfused patients; (2) to compare toxicity, response, and survival among patients who underwent melphalan-based perfusion with or without low-dose tumor necrosis factor (TNF); and (3) to identify factors that predict a complete response and survival. MATERIALS AND METHODS A total of 53 patients with extensive in-transit metastases (47%) underwent perfusion with melphalan, and 59 (53%) also received low-dose TNF. RESULTS No difference was observed between the 2 drug regimens for what concerns local toxicity (P = 1.0). The tumor complete response rate was higher in patients treated with TNF (60.3% versus 41.5%, P = .036), in particular in the case of locally advanced tumors (66.7% versus 30%, P = .049). The presence of lymph node metastases had a negative influence on the tumor response rate (P = .003). Median time to local progression and survival were 19.6 and 34.5 months, respectively. Long-term complete response was achieved in 68% of the patients with initial CR (39 of 57 patients). The tumor response after perfusion was the only prognostic factor for local control and survival (P < .0001 and P = .002, respectively). CONCLUSIONS In the case of locally advanced disease, the addition of low-dose TNF to melphalan-based isolated limb perfusion appears safe and particularly useful. The presence of lymph node metastases is associated with decreased response rates. A sustained complete response was obtained in about one-third of the patients.

Abstract
The incidence of malignant melanoma is increasing faster than any other cancer. In cases of recurrent melanoma confined to the extremities, hyperthermic isolated limb perfusion and isolated limb infusion provide a way to isolate the extremity and deliver a dose of chemotherapy several orders of magnitude higher than would be tolerated systemically. Although complete response rates of up to 80% for hyperthermic isolated limb perfusion and 44% for isolated limb infusion have been observed, there is still room for improvement and standardization in these two procedures in an attempt to optimize response while minimizing toxicity. Currently, new chemotherapy agents and small-molecule inhibitors are being investigated as a means of overcoming chemoresistance and improving response rates. In patients with advanced cutaneous disease confined to the extremities, evaluation of these new therapies can be very informative, as tissue acquisition at multiple treatment time points is easy owing to the superficial and multifocal nature of the disease. Through studying the biomolecular and genetic alterations in tumor tissue in response to these new therapies, genetically customized treatment regimens in which tumor resistance and sensitivity is predicted and treatment strategy is optimized before treatment begins may soon be available. Progress in regional therapy will prove not only beneficial for patients with disease confined to an extremity, but may also provide insight into developing novel treatment strategies for patients with systemic disease for whom current disease management options are poor.

Abstract
BACKGROUND Isolated limb perfusion (ILP) involves the administration of chemotherapy drugs directly into a limb involved by locoregional metastases. Unresectable locally advanced melanoma of the limbs represents one of the clinical settings in which ILP has demonstrated benefits. METHODS A systematic review of the literature on ILP for patients with unresectable locally advanced melanoma of the limbs was conducted. MEDLINE, EMBASE, and Cochrane database searches were conducted to identify studies fulfilling the following inclusion criteria: hyper- or normothermic ILP with melphalan with or without tumor necrosis factor (TNF) or other drugs providing valid data on clinical response, survival, or toxicity. To allocate levels of evidence and grades of recommendation the Scottish Intercollegiate Guidelines Network system was used. RESULTS Twenty-two studies including 2,018 ILPs were selected with a clear predominance of observational studies (90.90%) against experimental studies (9.10%). The median complete response rate to ILP was of 58.20%, with a median overall response rate of 90.35%. ILP with melphalan yielded a median complete response rate of 46.50%, against a 68.90% median complete response rate for melphalan plus TNF ILP. The median 5-year overall-survival rate was 36.50%, with a median overall survival interval of 36.70 months. The Wieberdink IV and V regional toxicity rates were 2.00% and 0.65%, respectively. CONCLUSIONS ILP is effective in achieving clinical responses in patients with unresectable locally advanced melanoma of the limbs. The disease-free and overall survival rates provided by ILP are acceptable. ILP is safe, with a low incidence of severe regional and systemic toxicity.

Abstract
Isolated limb perfusion is the preferred treatment option for locally advanced melanoma and sarcoma confined to a limb. This treatment results in high response rates with a satisfying duration of response in both tumours. A drawback of isolated limb perfusion, however, is the invasive and complex character of the procedure.Isolated limb infusion has been designed as a minimally invasive alternative to isolated limb perfusion. Treatment results of this simple technique, reported by various centres worldwide, show comparable response rates for melanoma and sarcoma. Therefore isolated limb infusion may replace isolated limb perfusion in the future as the preferred treatment option for these locally advanced limb tumours.

Abstract
BACKGROUND Isolated limb infusion (ILI) is a minimally invasive technique delivering regional chemotherapy to treat in-transit extremity melanoma. Determining perioperative factors that could predict toxicity is important to optimize strategies to improve clinical outcomes after regional chemotherapy in melanoma. METHODS Perioperative factors from 171 ILI patients performed at eight centers from 2001 to 2008 were reviewed. The Wieberdink limb toxicity scale and creatine phosphokinase (CK) levels were used to measure toxicity. Logistic regression analysis was used to estimate the association between toxicity and perioperative parameters. RESULTS Mild (grades I-II) and severe (grades >or=III) limb toxicity developed in 68% and 32% of patients, respectively. Melphalan adjusted for ideal body weight (aIBW) and papaverine were used in 47% and 63% of patients, respectively. Median peak CK for all patients was 563 U/l, and median peak occurred at postoperative day 4. On univariate analysis, papaverine and high CK levels (>563 U/l) were significantly associated with higher toxicity. On the contrary, aIBW was significantly associated with a lower risk of severe toxicity. Perfusate blood gas at 30 min [pH, PaO(2), and base excess (BE) ], limb temperature, and ischemia time were not predictive of limb toxicity. On multivariate analysis, severe toxicity was associated with female sex (P = 0.01), papaverine (P = 0.01), and high peak CK levels (P < 0.01). Independent predictors of high CK levels included younger age, unadjusted melphalan dose, and low PaO(2) at 30 min. CONCLUSIONS ILI can be performed with an acceptable morbidity. Papaverine use, female gender, and high peak CK were associated with higher limb toxicity. CK levels can be diminished significantly with aIBW.

Abstract
Hyperthermic isolated limb perfusion (HILP) and isolated limb infusion (ILI) may play a significant role in the treatment of patients with recurrent or in transit extremity melanoma or sarcoma that is unresectable. These procedures may be indicated when patients are otherwise faced with the possibility of a debilitating amputation. Not entirely benign treatment modalities, HILP and ILI can be associated with regional and systemic toxicities. We conducted a literature search of published studies using HILP and ILI for the treatment of extremity sarcomas and melanomas, and associated toxicities was performed. The regional toxicities of HILP and ILI are similar. The most common toxicities reported are mild to moderate. However, when severe regional toxicity occurs, albeit infrequently (<5%), fasciotomies or even amputation may be necessary. Some studies have showed a relationship between acute regional toxicities and long term regional morbidity. Systemic toxicity appears to be more frequent when TNF-alpha is used in combination with other drugs during HILP, however the use of TNF-alpha in the United States is limited to trials. Although regional toxicities are similar, systemic toxicity of ILI is minimal compared to HILP. ILI is easier to repeat, technically less complex, and may be more acceptable in infirmed patients. Long term morbidity and outcomes for ILI are still being evaluated. Both of these techniques may be suitable options in patients with unresectable advanced or recurrent, or in transit extremity melanoma or sarcoma.

Abstract
Background Unresectable recurrent and in-transit extremity melanoma presents a dilemma for the treating physician. While the disease is confined to the involved limb, the survival mimics that of multiple nodal metastases, with a 10-year survival rate of approximately 40%. This represents late-stage disease for which curative treatment options are limited. Methods To review the current treatment strategies for stage IIIB (N2c) in-transit and recurrent melanoma focusing on the options for unresectable disease, MEDLINE was searched for studies of known and experimental treatments for in-transit and recurrent extremity melanoma. Further results were obtained after review of the initial citations. Results For unresectable recurrences and in-transit metastases, therapies are limited to palliative (radiation), local (intratumoral injection, laser ablation and electroporation), regional (isolated limb perfusion/infusion), and systemic (chemotherapy) when local or regional techniques are not feasible. Conclusions In this patient population, intratumoral techniques have a limited role with current treatment regimens, but with the development of new drugs, these techniques may have more utility. If not contraindicated, regional techniques provide the greatest control and have minimal operative morbidity. Until new regimens are available, systemic therapy continues to be associated with considerable toxicity and only marginal response rates.

Abstract
BACKGROUND Isolated limb infusion (ILI) is a minimally invasive technique for delivering regional chemotherapy in patients with advanced and metastatic melanoma confined to a limb. It is essentially a low-flow isolated limb perfusion (ILP) performed via percutaneous catheters without oxygenation. METHODS From our prospective database 185 patients with advanced metastatic melanoma of the limb treated with a single ILI between 1993 and 2007 were identified. In all patients a cytotoxic drug combination of melphalan and actinomycin-D was used. Drug circulation time was 20-30 min under mild hyperthermic conditions (38-39 degrees C). RESULTS The majority of patients (62%) were female. Their average age was 74 years (range 29-93 years). Most patients had MD Anderson stage III disease (134/185). The overall response rate was 84% [complete response (CR) rate 38%, partial response rate 46%]. Median response duration was 13 months (22 months for patients with CR; P = 0.01). Median follow-up was 20 months and median survival was 38 months. In those patients with a CR, the median survival was 53 months (P = 0.005). CR rate and survival time decreased with increasing stage of disease. On multivariate analysis significant factors for a favorable outcome were achievement of CR, stage of disease, thickness of primary melanoma, the CO(2 )level in the isolated circuit, and a Wieberdink limb toxicity score of III (considerable erythema and edema). CONCLUSION The response rates and duration of response after ILI are comparable to those achieved by conventional ILP. ILI is a minimally invasive alternative to the much more complex and morbid conventional ILP technique for patients with advanced metastatic melanoma confined to a limb.

Abstract
In the seventies, limb-sparing surgery and radiation therapy appeared capable of successfully treating the great majority of adult patients with soft tissue sarcomas of the extremities. No survival benefit could be demonstrated in the patients selected for amputation. Microscopically positive surgical margins are related to a greater risk of local recurrence, whereas overall survival is compromised by high grade and large tumor size. Presurgery multidisciplinary discussion, management in reference center and management within cancer network independently predict conformity to the clinical practice guidelines. Reoperation should be a planned part of definitive management whenever the initial surgical procedure was done without a histologic diagnosis or was not planned to be a wide excision. Soft tissue flap reconstruction facilitates therapy for patients with locally advanced tumors so that patients with larger tumors can undergo resection, limiting complications and limb sacrifice. Vascular reconstruction is a feasible option in case of involvement of major vessels. Isolated limb perfusion (ILP) with TNF and chemotherapy is an efficient limb-sparing neoadjuvant therapy for locally advanced limb soft tissue sarcomas. Efficacy and safety of low-dose TNFalpha could greatly facilitate ILP procedures in the near future.

Abstract
OBJECTIVE The aim of this study is to describe the experience with 100 TNF-based ILP for locally advanced melanoma and to determine prognostic factors for response, time to local progression, and survival. METHODS One hundred TNF-based ILPs were performed between 1991 and 2003 in 87 patients for whom local control by surgery of in-transit melanoma metastases was impossible. In total, 62 iliac, 33 femoral, and 5 axillary ILPs were performed in mild hyperthermic conditions with 2 to 4 mg of TNF and 10 to 13 mg of melphalan per liter of limb volume. RESULTS Overall response was 95%, with 69% complete response, 26% partial response, and 5% no change. Complete response rate differed significantly for patients with IIIA disease versus IIIAB and IV. Local and systemic toxicity was mild to moderate in almost all cases, with no treatment-related death and one treatment-related amputation. Five-year overall survival was 32%; local progression occurred in 55% after a median of 16 months. In complete response patients, 5-year survival was 42% with local progression in 52% at a median of 22 months. Response rate and survival were significantly influenced by stage of disease; (local progression free) survival was influenced by response rate. CONCLUSIONS TNF-based ILP results in excellent response rates in this patient population with unfavorable characteristics. Response on ILP predicts outcome in patients and reflects aggressiveness of the tumor.

Abstract
INTRODUCTION Two to three percent of the patients with extremity melanoma develop in-transit metastases in the course of their disease. When local treatments fail, isolated limb perfusion (ILP) is a reasonable option, but is generally only applied to patients without evidence of distant metastases. We assessed the value of ILP in stage IV melanoma patients with symptomatic unresectable limb melanoma at our institutions. PATIENTS AND METHODS A computerized database, containing all patient, tumor, ILP, and follow-up data of 505 ILPs performed in 451 patients between 1978 and 2001, allowed the selection of eight (1.8%) stage IV patients who underwent a palliative ILP for unresectable melanoma lesions on the limbs. All patients had high tumor burden limb disease, according to the combined Fraker and Rossi criteria. RESULTS The overall tumor response rate was 88%, with 13% complete and 75% partial response rates. One patient did not respond to ILP. Three partial responding patients attained a complete remission (CR) after excision of the remaining limb lesions. The median duration of hospital stay was 12 days and acute regional toxicity was mild with slight erythema and edema in six and no signs of reaction in two patients. The median limb recurrence-free interval after CR was 6 months and the median duration from the time of distant metastases to death was 15 months. Overall ILP leads to the desired palliative effect in six patients (75%). CONCLUSION ILP should be considered as a palliative treatment in selected stage IV melanoma patients with symptomatic advanced limb disease.

Abstract
Although a few experimental approaches to isolated limb perfusion (ILP) are described in the literature, none of these animal models mimics the clinical perfusion techniques adequately to improve the technique of ILP on the basis of valid preclinical data. Therefore, we developed an ILP setup in rats allowing online monitoring of essential perfusion parameters such as temperature (in perfusate, various tissues, and rectum), pH (perfusate), perfusion pressure, and O(2) concentration (in perfusate, tissue), by a tailor-made data acquisition system. This setup permits close supervision of vital parameters during ILP. Various interdependencies, concerning the flow rate and the pressure of perfusate as well as tissue oxygenation were registered. For the measurement of pO(2) values in the perfusate and in different regions of the perfused hind limb, a novel type of microoptode based on quenching of a fluorescent dye was devised. Stable normothermic (37 degrees C) perfusion conditions were maintained at a constant perfusion pressure in the range of 40-60 mm Hg by administration of the spasmo lytic moxaverine (0.5 mg/mL of perfusate as initial dose) at a perfusate flow rate of 0.5 mL/min for 60 min. At the end of an ILP, there were no signs of tissue damage, neither concerning laboratory data (K(+), myoglobin, creatine kinase, lactic dehydrogenase) nor histopathological criteria. The reported ILP model is not only well suited to investigate the effects of hyperthermia but also to assess the efficacy of new antineoplastic approaches, when nude rats, bearing human tumours in the hind limbs, are used.

Abstract
Metastatic melanoma confined to a limb can be treated effectively by isolated limb infusion (ILI) with cytotoxic drugs. The present study was undertaken to determine whether electively performing a second ILI procedure after 4 weeks increases the frequency and/or duration of response, and also to assess the value of a second ILI when disease recurrence or progression in a limb occurs after a first ILI. In 47 patients, a planned double ILI protocol achieved an overall response (OR) rate of 88% (complete response (CR) 41%, partial response (PR) 47%, median duration of response 18 months). Response rates after double ILI were similar to those in 81 patients treated with a single ILI over the same time period (CR 41%, PR 41%), without significant differences in response duration. After double ILI more patients experienced Wieberdink Grade III or IV limb toxicity. Following a second ILI for progression after an initial ILI (n=14), the OR rate was 71%, with a 5 month median duration of response. Since elective double ILI increases toxicity without increasing efficacy, performance of a single ILI is the preferred treatment option for melanoma confined to a limb. However, a second ILI can be of value if limb disease recurs or progresses following a previous ILI.

Abstract
BACKGROUND The influence of isolated limb perfusion (ILP) on the limb recurrence-free interval (LRFI) and the number of lesions per recurrence was studied for patients with frequently recurring regional in-transit metastases previously managed by excisional surgery. METHODS All 43 patients who had their first ILP for a third or further limb recurrence were selected from our computer database of 451 patients who underwent therapeutic ILP for recurrent extremity melanoma in our centers. Eighteen patients had resectable and 25 had locally unresectable lesions at the time of ILP. The patients had a total of 269 intervals between treatment of their primary melanoma and last recurrence or last follow-up. Median follow-up was 35 months (interquartile range, 14-64 months). RESULTS The median LRFI decreases over time from primary melanoma to the third or further recurrence for which ILP was performed (P < 0.001). The median LRFI is 4.7 times longer (95% confidence interval [CI], 2.8-7.9; P < 0.001) after ILP in comparison with the last interval before ILP. Patients with resectable lesions have a median LRFI that is 5.9 times longer (95% CI, 2.7-13; P < 0.001). In all patients, the number of lesions increases by 22% per recurrence number (95% CI, 10%-35%; P = 0.02). At the same recurrence number, patients before ILP have a 2.6-fold higher (95% CI, 1.6-4.5) mean number of lesions than do patients after ILP (P < 0.001). CONCLUSIONS ILP lengthens the LRFI and decreases the number of lesions per recurrence significantly in patients with repeatedly recurrent limb melanoma. Therefore, ILP could be a valuable adjunct to excisional surgery for in-transit metastases in these patients whose LRFIs tend to shorten over time.

Abstract
BACKGROUND Hyperthermic isolated limb perfusion (HILP) with melphalan as treatment for locally recurrent or in-transit malignant melanoma is frequently performed but the principle for calculating drug dosage remains poorly understood. METHODS This study examined the pharmacokinetic profile of 14 consecutive patients to determine what variables were associated with toxicity and tumor responses. RESULTS Marked fourfold variability was noted in patient plasma melphalan concentrations. We defined a factor--the ratio of estimated limb volume (Vesti) to melphalan volume of distribution (Vss), Vesti/Vss--that was much more strongly correlated with acute regional toxicity than either area under concentration-time curve or peak plasma concentration. In addition, we found that AUX2 was the best correlate of tumor response. CONCLUSIONS Pharmacokinetic evaluation of prospective HILP trials is critical to not only understand response and toxicity outcomes but also to potentially improve the therapeutic index of regional perfusion.

Abstract
Isolated limb perfusion is a surgical procedure for delivering a high dose of chemotherapeutic or immunochemotherapeutic agent to a localised area, thus avoiding the severity of side-effects caused by systemic administration. This technique is generally used for treatment of patients with tumours of the limbs and extremities. We have done a systematic review of randomised controlled trials assessing the effectiveness of this treatment in patients with melanoma of the extremities. Four trials of 1038 patients met our inclusion criteria and were analysed. Although our analysis confirmed the reported increase in survival in two of the trials, neither had sufficient power to detect significant benefit for perfusion. Results from the trials showed that prophylactic perfusion has an equivocal effect on survival in patients with limb melanoma. Therefore, current evidence suggests that prophylactic isolated limb perfusion cannot be recommended as a routine adjunct to standard surgery in patients with high-risk primary limb melanoma, but only as a treatment for local disease control if other forms of locoregional therapy are not available.

Abstract
Hypoxic pelvic and limb perfusion by means of a balloon occlusion technique was evaluated in patients with recurrent melanoma of the lower limbs who were non-responders to isolated hyperthermic limb perfusion or who were not eligible for this procedure. A pilot study was performed in 17 patients, who underwent hypoxic pelvic and limb perfusion with 50 mg/m(2) of melphalan or 50 mg/m(2) of melphalan and 25 mg/m(2) of mitomycin C. Each procedure was followed by haemofiltration. A leakage monitoring study was performed in five of the 17 patients. The response rate and time to disease progression were the primary endpoints, with overall survival as the secondary endpoint. During the procedures there were no technical, haemodynamic or vascular complications, and no deaths occurred during surgery or in the postoperative period. Significant leakage (median 40%) was measured in the five patients studied. No severe systemic or regional toxicity was observed. After one course of treatment, the objective response rate was 47% (95% confidence interval 22.5-71.5%), the median time to disease progression was 10 months (range 2-40 months), and the 3 year overall survival was 20%. Hypoxic pelvic and limb perfusion seems to be a safe and effective treatment for patients with unresectable recurrent limb melanoma who are not eligible for isolated hyperthermic limb perfusion. Due to the non-homogeneity of the study, with some patients receiving a combination of melphalan and mitomycin C and others receiving only melphalan, it is not possible to make definite conclusions with regard to efficacy. Further studies are necessary to establish whether the response rates can be improved by using different drug regimens.

Abstract
Melanoma is a significant health problem. Despite public education and free cancer screenings, the incidence and mortality of melanoma continues to rise; however, many currently diagnosed melanomas are thin lesions, suggesting that education and awareness is having an impact. In addition, there are still subsets of patients who need increased surveillance in order to increase their survival. Although large congenital nevi may be precursors of melanoma, small and medium congenital nevi have an insignificant risk for melanoma development. Large congenital nevi, which are axial in location, appear to be more likely to develop melanoma and are associated with melanocytosis and melanoma of the CNS, both of which portend a poor prognosis. Recently, the recommended margins of excision have become more conservative so that many of the surgical defects can be closed primarily. Lymphoscintigraphy and sentinel node biopsy have replaced elective node dissections, thus decreasing the morbidity associated with the surgical management of melanoma. Although controversy still exists as to whether or not sentinel lymph node biopsy alters a patient's prognosis, it has been shown to be a powerful prognostic indicator. Although most melanomas are managed by routine surgical excision, other modalities are sometimes employed. For example, cryosurgery or radiation therapy may be indicated in the frail, elderly individual with a large facial lentigo maligna. Mohs surgery is the treatment of choice for head and neck melanomas and those located in areas where maximum preservation of tissue is required and for desmoplastic and acral lentiginous melanomas. Much more work remains in the area of adjuvant therapy, chemotherapy, and immunotherapy. Dacarbazine remains the drug of choice in disseminated melanoma, but remissions are usually short lived. Interleukin and biochemotherapy has yielded good results but the percentage benefiting is small. Although high dose interferon increases disease-free and overall survival in some patients, it remains a controversial drug which is not easily tolerated. In the new staging system for melanoma, ulceration is second only to Breslow's thickness. In transit (satellite) lesions have also been included in this new system. The new system also recognizes that patients with only microscopic metastatic nodal disease fare better than patients with clinically enlarged metastatic nodes and that it is the number of nodes involved with metastases, not their size, that determines the patient's prognosis. Except for lesions <1mm thick, the Clark's level of invasion has been de-emphasized.

Abstract
Isolated limb perfusion (ILP) is a well-established locoregional procedure to deliver high doses of cytostatics to an extremity with multiple in-transit lesions from cutaneous melanoma, with minimal systemic and mild local toxicity. This approach is quite sophisticated and requires accurate monitoring of systemic leakage and of the temperature of the affected limb in order to avoid major systemic and local side effects. Mephalan (L-PAM) is considered the reference drug, although complete responses are reported in only about 50% of patients. Since the early 1990s, tumor necrosis factor-alpha (TNF-alpha) was administered with melphalan in ILP aiming to improve the therapeutic index of this procedure. However, despite the impressive results reported, its role still remains controversial, seemingly confined to large tumor bulk. Fotemustine ILP was proposed as a less toxic alternative to L-PAM, after the results of a pilot experience claiming similar response rates with less local toxicity. A formal phase 1-2 study is now underway to confirm these findings. More straightforward procedures, such as isolated limb infusion, are appealing, as they seem capable of achieving good response rates, are easily repeatable, and are less costly. Larger series are required to validate such results. As potential agents to be delivered through ILP, new vasoactive drugs and agents with new mechanisms of action that interplay with chemotherapy, as well as virus-mediated gene therapy, are being developed.

Abstract
BACKGROUND Isolated limb perfusion (ILP) with cytotoxic agents is a remarkably effective but complex technique used to treat locally recurrent and metastatic melanoma confined to a limb. Isolated limb infusion (ILI), essentially a low-flow ILP performed without oxygenation via percutaneous catheters, has been developed as a simpler alternative. METHODS The outcome in 135 patients treated by ILI was reviewed. RESULTS The overall response rate in the treated limb was 85% (complete response [CR] rate 41%, partial response rate 44%). Median response duration response was 16 months (24 months for patients with CR). Median patient survival was 34 months. In those with a CR, the median survival was 42 months. CR rate and survival time decreased with increasing disease stage. Patients aged >70 years had a better overall response than younger patients. On multivariate analysis, factors associated with an improved outcome were a lower stage of disease, a final limb temperature >37.8 degrees C, and a tourniquet time >40 minutes. CONCLUSIONS The frequency and duration of responses after ILI were comparable to those achieved by conventional ILP. The ILI technique is particularly useful for older patients who might not be considered suitable for conventional ILP.

Abstract
BACKGROUND The treatment of patients with advanced or recurrent pelvic melanoma, which are often associated with lesions in the lower limbs, is still unsatisfactory and controversial. A simplified hypoxic pelvic and limb perfusion has been recently recommended to provide therapeutic options for palliation and possibly cure. METHODS A nonrandomized and noncontrolled phase II experimental study was performed in 11 patients with symptomatic unresectable recurrent melanoma of the pelvis and limb. Patients were submitted to hypoxic pelvic and limb perfusion with 25 mg/m(2) of melphalan, 50 mg/m(2) of cisplatin, 300 mg/m(2) of dacarbazine, and 75 mg/m(2) of epirubicin by means of a simplified balloon occlusion technique. Response rate and time to disease progression were the primary endpoints; overall survival was the secondary endpoint. RESULTS During the procedures there were no technical, hemodynamic, or vascular complications, and no deaths occurred during surgery or in the postoperative period. Response rate was 82% (95% confidence interval, 58% to 100%). Median time to disease progression was 12 months (range 9 to 30 months). Three-year overall survival was 34%. CONCLUSIONS Hypoxic pelvic and limb perfusion is a safe and good palliative treatment for patients with unresectable recurrent melanoma. Further studies are necessary to to confirm these data and to establish if refinements can be made with acceptable toxicity.

Abstract
This study sought to use a microdialysis technique to relate clinical and biochemical responses to the time course of melphalan concentrations in the subcutaneous interstitial space and in tumour tissue (melanoma, malignant fibrous histiocytoma, Merkel cell tumour and osteosarcoma) in patients undergoing regional chemotherapy by Isolated Limb Infusion (ILI). 19 patients undergoing ILI for treatment of various limb malignancies were monitored for intra-operative melphalan concentrations in plasma and, using microdialysis, in subcutaneous and tumour tissues. Peak and mean concentrations of melphalan were significantly higher in plasma than in subcutaneous or tumour microdialysate. There was no significant difference between drug peak and mean concentrations in interstitial and tumour tissue, indicating that there was no preferential uptake of melphalan into the tumours. The time course of melphalan in the microdialysate could be described by a pharmacokinetic model which assumed melphalan distributed from the plasma into the interstitial space. The model also accounted for the vascular dispersion of melphalan in the limb. Tumour response in the whole group to treatment was partial response: 53.8% (n = 7); complete response: 33.3% (n = 5); no response: 6.7% (n = 1). There was a significant association between tumour response and melphalan concentrations measured over time in subcutaneous microdialysate (P< 0.01). No significant relationship existed between the severity of toxic reactions in the limb or peak plasma creatine phosphokinase levels and peak melphalan microdialysate or plasma concentrations. It is concluded that microdialysis is a technique well suited for measuring concentrations of cytotoxic drug during ILI. The possibility of predicting actual concentrations of cytotoxic drug in the limb during ILI using our model opens an opportunity for improved drug dose calculation. The combination of predicting tissue concentrations and monitoring in microdialysate of subcutaneous tissue could help optimise ILI with regard to post-operative limb morbidity and tumour response.
