Abstract
Genomic and personalized medicine implementation efforts have largely centered on specialty care in tertiary health systems. There are few examples of fully integrated care systems that span the healthcare continuum. In 2014, NorthShore University HealthSystem launched the Center for Personalized Medicine to catalyze the delivery of personalized medicine. Successful implementation required the development of a scalable family history collection tool, the Genetic and Wellness Assessment (GWA) and Breast Health Assessment (BHA) tools; integrated pharmacogenomics programming; educational programming; electronic medical record integration; and robust clinical decision support tools. To date, more than 225,000 patients have been screened for increased hereditary conditions, such as cancer risk, through these tools in primary care. More than 35,000 patients completed clinical genetic testing following GWA or BHA completion. An innovative program trained more than 100 primary care providers in genomic medicine, activated with clinical decision support and access to patient genetic counseling services and digital healthcare tools. The development of a novel bioinformatics platform (FLYPE) enabled the incorporation of genomics data into electronic medical records. To date, over 4,000 patients have been identified to have a pathogenic or likely pathogenic variant in a gene with medical management implications. Over 33,000 patients have clinical pharmacogenomics data incorporated into the electronic health record supported by clinical decision support tools. This manuscript describes the evolution, strategy, and successful multispecialty partnerships aligned with health system leadership that enabled the implementation of a comprehensive personalized medicine program with measurable patient outcomes through a genomics-enabled learning health system model that utilizes implementation science frameworks.

Abstract
Cancer-associated thrombosis (CAT) is common and associated with mortality. We estimated CAT rate by cancer sites and inherited factors among cancer patients from the UK Biobank (N =70,406). The 12-month CAT rate after cancer diagnosis was 2.37% overall but varied considerably among cancer sites. Among the 10 cancer sites classified as 'high-risk' of CAT by the National Comprehensive Cancer Network guidelines, 6 had CAT rate <5%. In contrast, 5 cancer sites classified as 'average-risk' by the guidelines had CAT rate >5%. For inherited risk factors, both known mutation carriers in two genes (F5/F2) and polygenic score for venous thromboembolism (VTE) (PGSVTE) were independently associated with increased CAT risk. While F5/F2 identified 6% patients with high genetic-risk for CAT, adding PGSVTE identified 13 % patients at equivalent/higher genetic-risk to CAT than that of F5/F2 mutations. Findings from this large prospective study, if confirmed, provide critical data to update guidelines for CAT risk assessment.

Abstract
Background Studies of outpatients with mild or moderate COVID-19 are uncommon. We studied: 1) association of symptoms with reverse transcriptase polymerase chain reaction (RT-PCR) test results; and 2) association of initial RT-PCR cycle threshold (Ct) in relation to duration of RT-PCR positivity in outpatients with mild or moderate COVID-19. Methods This was a cohort study of outpatients with confirmed COVID-19 and at least one symptom. Participants had repeat nasopharyngeal swabs and symptom checklists every 3–5 days until two consecutive RT-PCR tests were negative. RT-PCR tests were used to assess viral load. Antibody tests for COVID-19 were performed at 2 weeks, 4 weeks, and 8 weeks after symptom onset. Results Twenty-five patients (nine females) were enrolled, ranging in age from 19–58 (median age 28 years). All patients reported at least one symptom, with a median of six symptoms per patient. Symptoms persisted for 6–67 days (median duration 18 days). In all 25 patients, blood samples collected a median of 13 days after symptom onset were positive for SARS-CoV-2 antibodies in 15 (60%). After a median of 28 days following symptom onset, 23/23 patients with available samples tested positive for antibodies. The longest duration of positive RT-PCR test was 49 days from first positive PCR test (Mean = 27.4, SD = 12.5, Median = 24). Initial Ct was significantly associated with longer duration (β = -1.3, SE = 0.3, p<0.01 per 1 cycle higher) of RT-PCR positivity. Conclusions In mildly or moderately ill COVID-19 outpatients, RT-PCT tests remained positive for as long as 49 days and test positivity and symptom duration correlated with initial viral load.

Abstract
BACKGROUND 13-Cis retinoic acid (13-CRA) is a synthetic vitamin A derivative. High-dose 13-CRA in patients with squamous cell cancers of the head and neck (SCCHNs) reduces the incidence of second primary tumors (SPTs). The authors report long-term results from a phase 3 randomized trial that compared treatment with low-dose 13-CRA versus placebo for patients who had early stage SCCHN, with a focus on the development of SPTs and overall survival (OS). METHODS In total, 176 patients who received treatment for stage I/II SCCHN were randomized to receive either low-dose 13-CRA (weight-based dose of 7.5 mg or 10 mg) or placebo for 2 years. A competing-risk approach and the log-rank test were used to compare the time to SPT and OS, respectively, between groups. RESULTS 13-CRA neither significantly reduced the cumulative incidence of SPT (P = .61) nor improved the time to SPT (hazard ratio [HR] for 13-CRA/placebo; 0.86; P = .61). Despite limited power, there was a trend toward improved OS for the 13-CRA arm (HR, 0.75; P = .14), particularly among patients whose index tumor was surgically excised (N = 26; HR, 0.50; P = .057) and among women (N = 39; HR, 0.44; P = .065) and never/former smokers (N = 129; HR, 0.61; P = .055), with a median follow-up of 16 years. The main 13-CRA related toxicities were dry skin and cheilitis. CONCLUSIONS Treatment with low-dose 13-CRA for 2 years did not decrease the incidence of SPT; subset analysis indicates a potential survival advantage among patients who are women and never/former smokers. More targeted interventions based on clinical risk factors and molecular characterization of tumors may yield greater success in future prevention trials.

Abstract
113 Background: The Living in the Future (LIFE) Cancer Survivorship Program at NorthShore University HealthSystem provides a risk adapted visit (RAV) directed by a physician and facilitated by an oncology nurse during which an electronic medical record documented LIFE survivorship care plan (SCP) is provided and discussed. We evaluated the degree to which a RAV promotes individualized healthcare and self-management as survivors transition from active treatment to follow-up care. Methods: Patients anonymously complete a post-RAV evaluation on the day of their RAV and then another at least one year after their RAV. Results: 1,713 RAVS, the majority for breast cancer, occurred from 1/2007 to 3/2014.There are 1,615 complete “day of” post- RAV evaluative data with a median time from completion of last therapy of < 6 months. Respondents scaled statements as strongly agree/ agree/disagree/ strongly disagree. Combined strongly agree/agree ratings are: 94% felt more confident in their ability to communicate information about their cancer treatments to other members of their healthcare team; 90% felt more comfortable recognizing signs and symptoms to report to their healthcare provider; 98% had a better appreciation for potentially helpful community programs and services. Of the 488 respondents (RAV between 1/2007 and 12/2012 n=1,366) to a questionnaire at least one year after the RAV, nearly 100%/97%/93%/91%/85% found the SCP useful in at least 1/2/3/4/5 ways: to summarize medical information, to reinforce follow up care, to recognize symptoms to report, to identify lifestyle practices that promote health, and for assistance in identifying local resources for support. 72% discussed their SCP with their PCP or another healthcare provider, 97% stated they made at least one positive lifestyle change, 89% attended at least one LIFE health promotion seminar, and 80% continue to work on wellness goals. Conclusions: Participation in a LIFE RAV following oncology treatment helps survivors construct a useful understanding of their cancer experience to guide self-care behavior. Data demonstrate that benefits persist one year after the visit and support the feasibility of a nurse-led RAV to establish a SCP in post-treatment cancer survivors.

Abstract
Abstract
Background: Experimental and epidemiologic data suggest that 3-hydroxy-3-methylglutaryl coenzyme A inhibitors (statins) have antitumor activity against colorectal cancer (CRC). We utilized data from the population-based Women's Health Initiative (WHI) cohort to assess whether statins are associated with a decreased risk of CRC.
Methods: The study population included 159,219 postmenopausal women ages 50-79 at baseline, in which 2,000 cases of CRC were identified over an average of 10.7 (2.9) years of follow-up. All cases of CRC were confirmed by review of medical records and pathology reports. Participants were asked to bring all current medications to their screening interviews and clinic staff entered information on statin use and other lipid lowering medications into the WHI database. Self- and interviewer-administered questionnaires were used to collect information on other CRC risk factors. Cox proportional hazards regression was used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). Analyses investigated the association of any statin use, type of statin, statin potency, and duration of use with CRC. Statistical tests were two-sided.
Results: Statins were used by 12,030 (7.6%) women in the cohort. The annualized rate of CRC was 0.13% among statin users and 0.12% among nonusers. The multivariable adjusted HR for statin users compared with nonusers was 0.99 (95% CI=0.83 to 1.20, p=0.95). There was no trend in risk of CRC by duration of statin use, with HR = 0.91 (95% CI=0.66 to 1.27) for < 1 years of use, HR = 1.28 (95% CI=0.97 to 1.68) for 1- < 3 years of use, and HR =0.79 (95% CI=0.56 to 1.11) for > 3 years of use. There was no relationship between type of statin use, statin potency (low, medium and high), or use of other lipid-lowering medications and CRC risk. In addition there was no relationship between statin use and tumor location (proximal, distal and rectal), or clinical features (tumor stage, grade or histology).
Conclusions: Statin use was not associated with a decrease in CRC risk in the WHI cohort.

Abstract
The polycomb group (PcG) protein, enhancer of zeste homologue 2 (EZH2), is overexpressed in several human malignancies including breast cancer. Aberrant expression of EZH2 has been associated with metastasis and poor prognosis in cancer patients. Despite the clear role of EZH2 in oncogenesis and therapy failure, not much is known about chemotherapeutics and chemopreventive agents that can suppress its expression and activity. Here, we show that dietary omega-3 (omega-3) polyunsaturated fatty acids (PUFAs) can regulate the expression of EZH2 in breast cancer cells. The treatment of breast cancer cells with omega-3 PUFAs, but not omega-6 PUFAs, led to downregulation of EZH2. Studies using proteosome inhibitor MG132 suggested that omega-3 PUFAs induce degradation of the PcG protein EZH2 through posttranslational mechanisms. Furthermore, downregulation of EZH2 by omega-3 PUFAs was accompanied by a decrease in histone 3 lysine 27 trimethylation (H3K27me3) activity of EZH2 and upregulation of E-cadherin and insulin-like growth factor binding protein 3, which are known targets of EZH2. Treatment with omega-3 PUFAs also led to decrease in invasion of breast cancer cells, an oncogenic phenotype that is known to be associated with EZH2. Thus, our studies suggest that the PcG protein EZH2 is an important target of omega-3 PUFAs and that downregulation of EZH2 may be involved in the mediation of anti-oncogenic and chemopreventive effects of omega-3 PUFAs.

PURPOSE To determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of gemcitabine using a fixed dose rate infusion (FDRI) in combination with gefitinib in patients (pts) with pancreatic adenocarcinoma (PCa). PATIENTS AND METHODS Patients with advanced PCa were given gemcitabine at the FDRI of 10 mg/m(2)/min IV on Days 1, 8, and 15 of a 28-day cycle. Dose levels of 1000, 1200, and 1500 mg/m(2) were evaluated. Oral gefitinib 250 mg was given daily. DLTs were defined as 2 instances of Grade 3 hematologic or 4 nonhematologic or any Grade 4 hematologic toxicity. At least 4 patients were treated at each dose level. Dose escalation occurred in the absence of DLTs. RESULTS Five women and 8 men were enrolled. Median age was 59 and performance status 1. All had metastatic disease. Four patients received prior adjuvant chemoradiation for PCa, and one chemotherapy for lung cancer. Median cycles were 4 per patient. The MTD was 1,200 mg/m(2). Toxicity was predominantly hematologic. At 1,500 mg/m(2), 1 patient had Grade 4 granulocytopenia and 3 patients Grade 3 granulocytopenia. Overall, 8 patients (60 percent) developed Grade 1 or 2 acneiform rashes. One patient had Grade 3 vomiting; no significant diarrhea or liver toxicity was seen. There were no objective responses seen. Median time to progression and overall survival were 4.57 months and 7.13 months, respectively. CONCLUSION Combining FDRI gemcitabine with gefitinib is feasible and tolerable. The recommended dose of gemcitabine is 1,200 mg/m(2) when used with gefitinib 250 mg daily.

Abstract
BACKGROUND With the general acceptance of lumpectomy, axillary staging, and radiotherapy as local treatment for infiltrating breast cancer, an appreciation is evolving for the spectrum of vascular lesions that occur in the mammary skin after this treatment. Most of these lesions develop within the prior radiation field after breast conservation treatment. STUDY DESIGN A retrospective chart and slide review was conducted, consisting of five patients with cutaneous vascular lesions after breast conservation treatment for infiltrating breast cancer. RESULTS The latent time interval from definitive treatment of breast cancer to the clinical recognition of vascular lesions ranged from 5 to 11 years. Two patients did not have either arm or breast edema, two patients had breast edema, and the fifth patient had arm edema. Lesions arising in the irradiated mammary skin included extensive lymphangiectasia (one), atypical vascular lesions (two), and cutaneous angiosarcoma (four). CONCLUSIONS Atypical vascular lesions at the skin margins of mastectomy may be predictive of recurrence after resection of angiosarcoma. Excision of skin from the entire radiation field may be necessary to secure local control of the chest wall in patients with cutaneous angiosarcoma after therapeutic breast radiotherapy.

Abstract
Menogaril is a semisynthetic anthracycline that is less cardiotoxic than doxorubicin in a preclinical model. We conducted a phase II trial to determine the activity of menogaril in hormone-refractory prostate cancer. Between October 1985 and November 1987, 32 eligible patients were enrolled and were divided into good- and poor-risk categories, the latter being defined by prior radiotherapy to less than one third of the marrow-containing skeleton. Good-risk patients received a starting dose of 200 mg/m2 by 60-minute IV infusion, whereas the poor-risk patients received 160 mg/m2. Treatment was repeated every 3 weeks until disease progression. Menogaril caused leukopenia in 90% of patients, of whom 47% had grade III or IV toxicity. Thrombocytopenia was uncommon and mild, with only three patients (9%) experiencing grade II toxicity. Nonhematologic toxicity included mucositis (9%), and mild weight loss in 33% of patients. Nine patients (28%) had stable disease of 3 or more months' duration. There were no objective partial or complete responses. The median time to progression for the entire group was 10 weeks, and the median survival time for all patients was 24 weeks. Because of appreciable toxicity and limited antitumor activity, further study of menogaril cannot be recommended in hormone-refractory prostate cancer.

Abstract
A quantitative multiplex RT-PCR assay is described to measure the levels of messenger RNAs for eight human genes encoding the heat shock proteins (HSP) and molecular chaperones hsp90alpha, hsp90beta, hsp70, hsc70, mtHsp75, Grp78 (BiP), hsp60 and hsp27. The basis of this assay is reverse transcription of total RNA isolated from human cells followed by amplification with PCR. By the careful selection of pairs of oligonucleotide primers corresponding to unique regions of each heat shock gene, selectivity can be attained such that messenger RNAs of multiple heat shock genes can be analyzed simultaneously in a single reaction. This method provides both the absolute and relative levels of each heat shock message by including in the reaction, reference control RNAs corresponding to in vitro transcripts of heat shock gene plasmids carrying small internal deletions.

Abstract
The authors assess the activity and toxicity of paclitaxel in previously untreated patients with multiple myeloma. Eighteen patients with previously untreated multiple myeloma were enrolled. Paclitaxel was given in a dose of 250 mg/m2 by a continuous intravenous infusion for 24 hours every 21 days for four cycles. All patients received granulocyte colony stimulating factor in a dose of 5 microg/kg each day until the absolute neutrophil count was 10,000/mm3. All patients were evaluated after four cycles. Four (29%) objective responses were observed in the 14 eligible patients. No complete responses occurred. Three lethal toxicities were observed, two were the result of neutropenic sepsis. Sixty-one percent of patients experienced some type of severe nonhematologic toxicity. Patients who received four cycles of paclitaxel were given further treatment at the discretion of the investigator. The median survival of all eligible patients was 2.8 years, which is comparable with the median survival with melphalan and prednisone of 2.3 years or vincristine, carmustine, melphalan, cylophosphamide, and prednisone of 2.4 years. Paclitaxel in the dosage used in this study has prohibitive toxicity. The four (29%) responses in 14 evaluable untreated patients indicates that paclitaxel is active in the treatment of multiple myeloma. No complete remissions were recorded. Further studies using paclitaxel in a smaller dose, in combination with other agents, or using one of the paclitaxel analogs may be useful in the treatment of multiple myeloma.

Abstract
Follow-up of breast cancer patients who have completed their primary therapy has not been standardized. The literature is reviewed and it is proposed that "minimal" follow-up with history and physical examination is the most appropriate procedure. Data show that more expensive imaging studies be carried out only in patients who are symptomatic from their disease, otherwise such an intensive follow-up schedule is not cost effective.

Abstract
BACKGROUND Malignant pleural effusions are seen frequently in clinical practice and are most commonly caused by breast cancer and lung cancer. Standard treatment usually consists of complete drainage of the pleural space via a chest tube and instillation of a pleural irritant to obtain pleural symphysis. In a majority of instances, such treatment effectively controls the pleural space; however, standard treatment fails in some cases. METHODS Twenty-four patients who did not respond to standard treatment for malignant pleural effusion were subjects for parietal pleurectomy, which was usually performed through an axillary thoracotomy. In several cases, decortication was also necessary. The study population was composed of 18 women and six men. Twelve of the patients had carcinoma of the breast, five carcinoma of the lung, and four carcinoma of the ovary. RESULTS Three patients died in the perioperative period to give an operative mortality of 12.5%. The other 21 patients all had satisfactory control of their recurrent malignant effusions. Their survival time ranged from 2 to 30 months (average 10.6). CONCLUSIONS Parietal pleurectomy is an effective operation for recurrent malignant pleural effusion. However, because of its significant morbidity and mortality, it should be reserved for failures of standard treatment, and patient selection is important.

Abstract
Thirty-three patients with advanced colorectal carcinoma were entered on a phase II trial of weekly IV aminothiadiazole (175 mg/m2 escalated to 200 mg/m2) with concomitant allopurinol and non-steroidal anti-inflammatory agents (NSAID's). Toxicity was predominantly GI, cutaneous, and chest pain/dyspnea. Twenty-five percent of patients had grade 3 or 4 toxicity. There were no responses in 27 evaluable patients. Median survival was 12 months. Aminothiadiazole, at higher doses than used in previous reports, when given with NSAID's, had no significant activity against large bowel cancer.

Abstract
PURPOSE To evaluate the feasibility of integrating a program based on dietary fat intake reduction into adjuvant treatment strategies for postmenopausal women receiving therapy for early breast cancer. PATIENTS AND METHODS Two hundred ninety postmenopausal women with localized (stage I to IIIa) breast cancer receiving conventional systemic therapy provided informed consent and were randomized in a multicenter trial to either a dietary intervention group receiving a program of individualized instruction for reducing total fat intake or a dietary control group with minimal dietary counseling. RESULTS Significantly reduced (P < .001) fat intake (in terms of percent calories derived from fat) was observed in the intervention group versus the control group at 3 months (20.3% +/- 2.4% v 31.5% +/- 2.6%, mean +/- SD, respectively) and maintained throughout 24 months of observation. The 50% reduction in daily fat-gram intake (from 66 +/- 23 to 33 +/- 14 g, P < .001) seen at 6 months was associated with reduced saturated fat, monounsaturated fat, polyunsaturated fat, and linoleic acid (P < .001). Significantly lower body weight was also seen in intervention compared with control patients at all observation periods, resulting in a 3.3-kg weight difference 18 months after randomization (P < .001). CONCLUSION Substantial and sustained dietary fat reduction with associated weight change can be achieved at relatively low cost within the context of conventional multimodality clinical management of postmenopausal women with localized breast cancer. This result supports the feasibility of conducting a full-scale evaluation of the influence of dietary fat intake reduction on the clinical outcome of breast cancer patients.

Abstract
The authors report the first instance of a patient with seminoma probably arising from the prostate but also involving the bladder. A 58-year-old man presented with symptoms and signs of prostatic enlargement. Cystoscopy revealed a fungating neoplasm, probably arising from the prostate and surrounding the bladder neck. The biopsy was consistent with the diagnosis of seminoma. The patient experienced complete remission after chemotherapy with bleomycin, cisplatin, and etoposide.

Abstract
A single institution, retrospective study of 28 patients with inflammatory carcinoma of the breast treated from 1984 to 1990 was performed. Patients received two to four cycles of cyclophosphamide, doxorubicin and 5-fluorouracil (CDF) and were then evaluated for mastectomy. Mastectomy was accomplished in 26 patients after CDF. In 21 patients, the breast was resectable after the initial doses of chemotherapy and modified radical mastectomy was done. Radiation therapy was given to 16 of the 21 patients after six to nine cycles of postoperative chemotherapy. The remaining five of 26 patients had a marginal response to CDF and underwent preoperative radiation therapy. Local recurrence occurred in four of five patients receiving preoperative radiation, in three of 16 receiving postoperative radiation and in one of five receiving mastectomy without radiation therapy. The overall observed five year survival rate was 18 percent, with a median of 34 months. Neither dermal lymphatic invasion nor estrogen receptor status were statistically significant variables when analyzing patients for local recurrence or survival. Despite poor long term survival results, the combination of induction CDF, mastectomy and postoperative radiation achieved local control in 81 percent of patients.

Abstract
This is a comparative study to evaluate response rate to mitoguazone (MGBG) and vinblastine (VLB) in 52 evaluable patients with advanced transitional cell carcinoma of the urinary tract. Of 38 patients with measurable disease, two of 18 (11%) on MGBG had partial remission (95% confidence interval: 0.01, 0.35), whereas four of 20 (20%) responded on the VLB arm (95% confidence level: 0.06-0.44). Both responses on the MGBG arm were seen in patients given prior chemotherapy. Side effects of both drugs were significant, with 46% of patients given VLB developing severe or life-threatening hematologic toxicity. Data indicate that both drugs, as single agents, are probably inferior to cisplatin for control of advanced transitional cell carcinoma of the urinary tract.

Abstract
Sixty-six women with advanced ovarian carcinoma of coelomic epithelial origin were randomly assigned to one of two intravenous single-agent infusion treatment regimens, either acivicin (60 mg/m2/course, administered as a 72-hr infusion) or vinblastine (7.5 mg/m2/course, administered as a 120-hr infusion) every three weeks. All had progressive disease after one to three prior chemotherapeutic regimens. Of 62 patients who were evaluable for response, survival and toxicity, there was one partial response (2%) produced by vinblastine. Median survival was 13 weeks on either treatment arm. Three patients (10%) on the acivicin arm experienced life-threatening myelosuppression. Severe toxicities resulting from this treatment included myelosuppression (26%), neurotoxicity (16%), mucositis (3%) and vomiting (6%). Vinblastine was associated with one lethal pneumonia and five cases of life-threatening myelosuppression (16%); severe toxicities included myelosuppression (58%), genitourinary toxicity (6%), infection (3%), and edema (3%). Neither regimen produces useful clinical results in patients who have relapsed after prior chemotherapy for ovarian carcinoma.

Abstract
We treated 103 patients with histologically confirmed anaplastic supratentorial astrocytic neoplasms with either diaziquone (AZQ) and carmustine (BCNU) or AZQ and procarbazine. There were 74 patients with glioblastoma multiforme (GBM) and 29 patients with anaplastic astrocytoma (AA). AZQ plus BCNU produced partial (PR) or unequivocal responses in seven of 32 (21.9%) patients with GBMs and three of ten (30%) patients with AAs. Two patients with GBMs (6.3%) and five patients with AAs (50%) showed stable disease (SD). AZQ plus procarbazine produced PRs or unequivocal responses in five of 42 (11.9%) patients with GBMs and nine of 19 (47.4%) patients with AAs. Eight patients with GBMs (19%) and one patient with an AA (5.2%) showed SD. In addition to histologic diagnosis, only the Karnofsky performance-status (KPS) rating independently influenced response and survival. Differences in response rates between the two regimens were not significant, although estimated median survival after adjusting for performance status was slightly better with AZQ plus BCNU than with AZQ plus procarbazine (P = .031). Neither age nor prior chemotherapy were significant independent risk factors. Toxicity was mild and primarily hematologic. We conclude that these AZQ-based regimens have activity in patients with recurrent anaplastic gliomas, but that they are not clearly superior to other agents in current use. The histologic diagnosis of GBM is associated with a significantly worse prognosis than AA, and we believe that this important distinction must be recognized in phase II as well as phase III trials.

Abstract
A spontaneously metastasizing solid tumor model derived by transplanting the TA3Ha murine mammary carcinoma into the s.c. tail tissue of mice was used to develop a treatment strategy for enhancing the therapeutic efficacy of cisplatin (CDDP). This strategy was based on the findings that diethyldithiocarbamate (DDTC) reduces the toxicity of CDDP, and that localized hyperthermia (HT) augments the antitumor efficacy of CDDP. DDTC (500 mg/kg) reduced the CDDP-induced nephrotoxicity and gastrointestinal toxicity as well as increased the CDDP LD10 from 8 to 20 mg/kg in strain A mice. When CDDP and DDTC were used in multiple treatment schedules at 5-day intervals, DDTC protected the hosts but not the tumors against the toxicity of CDDP. HT administered locally to the tumor 1 h after the injection of CDDP (8 mg/kg) in 1 ml Hanks' balanced salt solution increased the antitumor effect but not the host toxicity. While administration of 8 mg/kg CDDP alone or with HT three times at 5-day intervals caused 100% host mortality, this dose of CDDP could be used with no mortality by combining it with DDTC. A combination of 8 mg/kg CDDP with DDTC (750 mg/kg) and HT (43 degree C for 60 min), administered three times at 5-day intervals, retarded the local tumor growth significantly compared to the untreated, CDDP plus DDTC plus HT control groups of mice. The frequency of lung metastasis in these groups on day 30 of tumor inoculation were 0, 90, 90, and 80%, respectively. The mean survival days of the mice treated with CDDP plus DDTC plus HT was 61 +/- 6 compared to 34 +/- 5 in the controls. The results presented here demonstrate that by combining CDDP with DDTC, high doses of CDDP can be safely administered. When localized HT is combined with high dose CDDP and DDTC, the tumor growth retardation and the host survival prolongation are significantly better than those obtained with the highest tolerable dose of CDDP alone or CDDP plus HT.

Abstract
In a recall clinic for patients at risk for thyroid carcinoma due to a history of radiation in infancy or childhood, a group of patients were randomly offered prospective suppressive L-thyroxine therapy and matched to a radiated nontreated group. With an average of more than two years' follow-up, the thyroid hormone-treated radiated group developed fewer nodules and abnormalities to palpation and also had a statistically significant lessening of minimal palpable abnormalities compared to the nonthyroxine-treated radiated group.

Abstract
We conducted a Phase II study of combination therapy with vincristine and cyclophosphamide in the treatment of patients with recurrent or metastatic medulloblastoma. Fourteen patients were treated with vincristine 2 mg/m2 (2.0-mg maximal dose) by intravenous bolus on Day 1 and cyclophosphamide 1 g/m2 by intravenous infusion on Days 1 and 2, with cycles repeated every 4 weeks. All 4 patients with extraneural disease (biopsy-proven bony metastases) responded (duration of responses 2+, 6+, 8, and 16+ months) and 4 of 8 evaluable patients with neuraxis disease responded (duration of response 2, 2+, 2+, and 21+ months). Toxicity was limited to neutropenia without any episodes of infection. These therapeutic results compare favorably with other reports of therapy for recurrent medulloblastoma and support the inclusion of vincristine and cyclophosphamide in randomized adjuvant therapy trials of patients with medulloblastoma.

Abstract
trans-Diamminedichloroplatinum(II), a paradigm of an inactive platinum compound, exhibited cytotoxic effect against HEP-2 human tumor cells, TA3Ha murine tumor cells, and freshly collected human ovarian carcinoma cells when combined with hyperthermia (43 degrees, 30 min). The heat treatment reduced the D0 of trans-platinum from 56 to 16.5 micrograms/ml in the HEP-2 system and from an undeterminable value at 37 degrees to 8.2 micrograms/ml in the TA3Ha system. Heat treatment before trans-platinum was more cytotoxic than that after trans-platinum in the TA3Ha system (P less than 0.001). TA3Ha cells treated in vitro with 40 micrograms/ml TDDP at 43 degrees failed to form tumors in mice upon subcutaneous implantation into the tails of mice. In contrast, these agents given singly did not alter the tumor-forming ability of TA3Ha cells. In vivo administration of trans-platinum after hyperthermia (43 degrees for 30 min) retarded the growth of TA3Ha tumors compared to either treatment alone. trans-Platinum did not form detectable DNA-interstrand cross-links in the HEP-2 cells treated at 37 degrees or 43 degrees. However, the DNA-protein cross-links were detectable under these conditions. The frequencies of DNA-protein cross-links were higher in the cells treated at 43 degrees than in those treated at 37 degrees, both immediately after and 12 h after the treatment with trans-platinum. Heat alone did not induce the formation of either DNA-interstrand or DNA-protein cross-links. Heat treatment did not appear to enhance the entry of trans-platinum into the cells.

Abstract
Aziridinylbenzoquinone (AZQ) was studied in a Phase II protocol for persons with glioma of the central nervous system (CNS) recurrent or progressive after surgery and radiotherapy. Patients received AZQ, 30 mg/m2 intravenously every 3 weeks if previously untreated or 27.5 mg/m2 if previously exposed to cytotoxic drugs. Partial response was defined as a reduction of at least 50% reduction in the product of the two longest perpendicular diameters of the indicator lesion persisting for a minimum of 28 days. Twenty-eight patients are evaluable for response at this time. Objective response (OR) occurred in four (14.3%): two complete and two partial. Stabilization of disease (SD) was seen in 7 (25.0%). Median survival, in weeks, was greater than 46.0 for responders, 41.7 for SD, and 19.3 for those with progressive disease. The survival experiences are significantly different (P = 0.030 [Breslow]). The OR rate was 21.1% in 19 without prior chemotherapy and 0% in 9 previously treated patients. There were two AZQ-related deaths in patients with prior exposure to nitrosoureas (1 CNS hemorrhage; 1 aspiration pneumonia). One patient had an anaphylactic reaction. Three patients whose tumor initially increased in size subsequently had marked tumor shrinkage. AZQ is an active agent that must be used with added caution in patients who have received nitrosoureas. Initial tumor enlargement may precede response. Although response appears to prolong survival, the correlation between stabilization of disease and survival is not well-defined.

Abstract
Nine US institutions performed 14,807 Phase I-II treatments of magnetic-induction (Magnetrode [Henry Medical Electronics, Inc., Los Angeles, CA]) hyperthermia in 1170 adults. All had advanced tumors: 20% had untreated inoperable cancer or disease progression despite surgery (10%), radiation therapy (XRT) (3%), chemotherapy (27%), or combinations (40%); 67% had pain; and 79% had reduced activity. Eighteen percent were advanced primaries, 26% were recurrent, and 56% metastatic tumors in the head and neck (7%), body wall (7%), extremity (4%), abdominal cavity (17%), pelvis (17%), lung (15%), or liver (30%); 36% were less than 5 cm and 64% greater than or equal to 5 cm. Treatments were to safe tolerance for 30 to 60 minutes for five or more treatments. Results in 960 evaluable patients were complete response 9% (1-34 months; median, 7 months), partial response 18% (1-39 months; median, 4 months), minimal response 10% (1-15 months; median, 3 months), and no change 33% (1-32 months; median, 3 months), with decreased pain in 30% and improved activity in 21%, independent of histologic type or site. Regression was dependent on treatment type and minimum temperature: heat only, 23%; heat + XRT, 60%; heat + less-than-standard XRT because of prior XRT failure, 39%, heat + intravenous (IV) chemotherapy, 28%; heat + same previously failed IV chemotherapy, 20%; heat + intraarterial (IA) chemotherapy, 28%; heat + same previously failed IA chemotherapy, 15%; heat + standard XRT + chemotherapy, 58%; heat + less-than-standard XRT + chemotherapy, 47%; less than 40 degrees C, 31%; 40 to 40.9 degrees C, 45%; 41 to 41.9 degrees C, 54%; 42 to 42.9 degrees C, 47%; 43 to 43.9 degrees C, 40%; 44 to 44.9 degrees C, 33%; 45 to 45.9 degrees C, 55%; 46 to 46.9 degrees C, 63%; greater than 47 degrees C, 100%. There were 49 (0.33%) skin burns and 2 systemic injuries (stomach ulcer at 1 month; lung fibrosis at 9 months). This trial indicates that localized hyperthermia has a significant role in palliation of human advanced solid cancer.

Abstract
Malignant pericardial effusion can result in acute cardiac tamponade with serious hemodynamic compromise. This condition requires prompt pericardial decompression for relief of symptoms; however, the risks of general anesthesia in this setting are considerable. In a series of 12 patients, all operated on under local anesthesia without operative mortality, there were six patients with malignant pericardial effusion secondary to lung carcinoma; four patients, secondary to breast carcinoma; one patient, secondary to squamous cell carcinoma of the oral cavity; and one patient, secondary to an unknown primary. The clinical presentation of each was abrupt and echocardiography was definitive. The procedure is performed through an upper abdominal midline incision. The xiphoid process is excised, the diaphragm is visualized, and a pericardial window is created through which two chest tubes are placed through separate stab incisions. The tubes are removed when the drainage has subsided, usually 3-7 days. No medication or irritant is instilled. There was no recurrence following this treatment. The average survival time was 27 weeks with a range of 2-153 weeks. This operation should be part of the repertoire of the general surgeon who treats breast cancer and of the thoracic surgeon who treats lung cancer.

Abstract
From October 1978 to October 1981, 135 patients with disseminated transitional cell carcinomas of the urinary tract, with either measurable or evaluable disease, were randomized to receive either cis-diamminedichloroplatinum (DDP) or cyclophosphamide (CTX), Adriamycin (ADR) (Adria Laboratories, Columbus, Ohio), and DDP (CAD). DDP was given at a dose of 60 mg/m2, CTX at 400 mg/m2, and ADR at 40 mg/m2 intravenously every three weeks. Patients over the age of 65 and those with prior radiation received 75% of the dose initially. The dose was escalated if only mild toxicity developed. Of the patients on the CAD arm, 34% developed grade 3 or 4 hematologic toxicity, as compared to 3% in patients on the DDP therapy. Of the 93 patients with measurable disease, 48 received DDP. Seventeen percent had a partial or complete remission, as compared to 33% of the 45 patients on the CAD arm (P = .09). The crude median survival of patients on DDP was 6.0 months as compared to 7.3 months in patients receiving CAD (P = .17). We conclude that the CAD combination is more toxic than DDP with, at best, very marginal benefit in survival.
