Abstract
OBJECTIVE Nintedanib is an oral tyrosine kinase inhibitor targeting, among others, vascular endothelial growth factor receptor. The aim was to establish the role of nintedanib in addition to paclitaxel and carboplatin in first-line recurrent/metastatic cervical cancer. METHODS Double-blind phase II randomized study in patients with first-line recurrent or primary advanced (FIGO stage IVB) cervical cancer. Patients received carboplatin-paclitaxel with oral nintedanib 200 mg BID/placebo. The primary endpoint was progression-free survival (PFS) at 1.5 years and α = 0.15, β = 80%, one sided. RESULTS 120 patients (62 N, 58C) were randomized. Median follow-up was 35 months. Baseline characteristics were similar in both groups (total population: squamous cell carcinoma 62%, prior radiotherapy 64%, primary advanced 25%, recurrent 75%). The primary endpoint was met with a PFS at 1.5 years of 15.1% versus 12.8% in favor of the nintedanib arm (p = 0.057). Median overall survival (OS) was 21.7 and 16.4 months for N and C, respectively. Confirmed RECIST response rate was 48% for N and 39% for C. No new adverse events were noted for N. However, N was associated with numerically more serious adverse events for anemia and febrile neutropenia. Global health status during and at the end of the study was similar in both arms. CONCLUSION The study met its primary endpoint with a prolonged PFS in the N arm. No new safety signals were observed.

Abstract
Despite screening programs for early detection and the approval of human papillomavirus vaccines, around 6% of women with cervical cancer (CC) are discovered with primary metastatic disease. Moreover, one-third of the patients receiving chemoradiation followed by brachytherapy for locally advanced disease will have a recurrence. At the end, the vast majority of recurrent or metastatic CC not amenable to locoregional treatments are considered incurable disease with very poor prognosis. Historically, cisplatin monotherapy, then a combination of cisplatin and paclitaxel were considered the standard of care. Ten years ago, the addition of bevacizumab to chemotherapy demonstrated favorable data in terms of response rate and overall survival. Even with this improvement, novel therapies are needed for the treatment of recurrent CC in first as well as later lines. In the last decades, a better understanding of the interactions between human papillomavirus infection and the host immune system response has focused interest on the use of immunotherapeutic drugs in CC patients. Indeed, immune checkpoint inhibitors (pembrolizumab, cemiplimab, and others) have recently emerged as novel therapeutic pillars that could provide durable responses with impact on overall survival in patients in the primary (in addition to chemotherapy) or recurrent (monotherapy) settings. Tisotumab vedotin, an antibody–drug conjugate targeting the tissue factor, is another emerging drug. Several trials in monotherapy or in combination with immunotherapy, chemotherapy, or bevacizumab showed very promising results. There is a high need for more potent biomarkers to better accurately determine which patients would receive the greatest benefit from all these aforementioned drugs, but also to identify patients with specific molecular characteristics that could benefit from other targeted therapies. The Cancer Genome Atlas Research Network identified several genes significantly mutated, potentially targetable. These molecular data have highlighted the molecular heterogeneity of CC. The majority of recurrent or metastatic CCs are considered incurable disease. Combination of chemotherapy with bevacizumab and pembrolizumab (PD-L1 CPS ≥1) is the new standard of care in first line. Tisotumab vedotin, an antibody–drug conjugate targeting the tissue factor, is another emerging drug. Need for more potent biomarkers to accurately determine which patients would receive the greatest benefit from these drugs.

Abstract
Ovarian cancer (OC) has a poor prognosis as most patients present with non-specific symptoms and the disease is mostly diagnosed at advanced stages. Approximately 90% of cases are classified as epithelial OC (EOC), a category comprising histologically and molecularly distinct tumours. Identifying reliable biomarkers and employing personalised therapies in OC subgroups is crucial for battling the disease. EOCs are often characterised by homologous recombination repair deficiency (HRD), frequently caused by inactivation of the breast cancer susceptibility (BRCA) genes. These findings have led to the development of poly- (adenosine diphosphate [ADP])- ribose polymerase inhibitors (PARPi), which are synthetically lethal to HRD tumour cells. Both patients with HRD and non-HRD tumours can benefit from PARPi therapy in the recurrent setting. Moreover, recent phase III trials in patients with newly diagnosed advanced-stage OC have demonstrated greater clinical benefit from PARPi in treating HRD than non-HRD tumours. These findings offer new opportunities for the use of PARPi as maintenance therapy after first-line chemotherapy based on the presence of HRD. In the current article, we provide recommendations for HRD testing and treatment of patients with newly diagnosed advanced-stage EOC.

Abstract
The use of mega-joint prostheses has become common practice in the field of reconstructive orthopedic surgery. These new implants are considered as the gold standard for reconstruction after joint and periarticular tumor and bone resections. The placement of these prostheses makes it possible, compared to an amputation, to preserve the pathological limb, but also to be able to ensure a solid assembly allowing immediate support and a quick functional recovery. However, the incidence of various complications following the placement of these implants remains higher compared to conventional joint replacement surgery. The most frequent can be classified into two distinct categories: mechanical and non-mechanical complications.

Abstract
Cervical cancer is the fourth most common cancer in women and is linked in over 95 % of cases to papillomavirus infection, the incidence of which has fallen in recent years due to screening and vaccination. Almost half of these cancers are diagnosed at a locally advanced stage with an overall 5-year survival of around 65 %. In recent decades, the management strategy of these locally advanced cancers has changed considerably and has allowed the improvement of survival but above all of local control as well as the reduction of toxicity, due to the implementation of imaging. Standard treatment consists of external beam radiation therapy combined with concomitant chemotherapy followed by intrauterine brachytherapy. The role of neo-adjuvant and adjuvant chemotherapy is still being evaluated. New therapeutic approaches (particularly immunotherapy) in addition to standard treatment are also being studied.

Abstract
Most ovarian cancer patients are diagnosed only at advanced stages when survival outcomes are worse, andwhen therapeutic decisions might prove challenging. The fundamental treatment for women with ovarian cancerincludes debulking surgery whenever possible and appropriate systemic therapy (chemotherapy, targeted andantiangiogenic agents). In the last few years, knowledge about histological and molecular characteristics of ovariancancer subtypes and stages has increased considerably. This has enabled the development and improvement ofseveral options for the diagnosis and treatment of ovarian cancer in a patient-tailored approach. Accordingly,therapeutic decisions are guided by the characteristics of the patient and the tumour, especially the molecularfeatures of the cancer subtype and disease stage. Particularly relevant are the advances in early genetic testing ofgermline and somatic mutations involved in DNA repair, and the clinical development of targeted agents. In orderto implement the best individual medical strategies, in this article, we present an algorithm of treatment options,including recently developed targeted agents, for primary and recurrent ovarian cancer patients in Belgium.

Abstract
Carcinomas of unknown primary (CUP) form a whole group of heterogeneous neoplasias. CUP are defined as metastatic epithelial tumors in which the initial work up has failed to detect the primary site. Their frequency is 3-5 % of the adult solid neoplasias. The prognosis is poor with a life expectancy of a few months (inferior to 1 year). The treatment depends on the histology and, particularly, on the metastatic localiza¬tion. Surgery with or without radiotherapy is the preferred treatment option for isolated lesions. Systemic chemotherapy (with platinum compound) will be recommended for multiple lesions. The genetic expression profile of tumor cells could be useful in the future to determine the site of the primary tumor and/or to offer the best therapy for each patient.

Abstract
The incidence of cancer is raising and the treatments are increasingly aggressive. Consequently, general practitioners, emergency departments, hematologists and oncologists are regularly facing a severe side-effect of cytotoxic therapy, febrile neutropenia (FN). FN is a serious complication of chemotherapy because it can be quickly fatal and causes a temporary or definitive cessation of treatment. In this article, we summarize the latest recommendations for the management of patients with FN under anti-cancer treatments.

Abstract
Docetaxel chemotherapy is a standard treatment for fit men with symptomatic castration-resistant prostate cancer. Unfortunately docetaxel resistant disease will systematically develop and second-line treatment may be appropriate. Until recently no standard treatment was approved in this setting and mitoxantrone was commonly used. Three new drugs have shown benefit in randomised phase 3 multicenter clinical trials published since 2010. Cabazitaxel, abiraterone and enzalutamide were shown to prolong overall survival of men with metastatic castration-resistant prostate cancer previously treated with chemotherapy. Although still modest these results were deemed clinically significant and led to the reimbursement of Jevtana (cabazitaxel) and Zytiga (abiraterone) in Belgium in 2012.

Abstract
Peritoneal carcinomatosis is defined as a secondary neoplastic invasion of the peritoneum. This entity may represent a significant challenge in terms of its diagnosis, its exploration and research of its origin and its treatment. This clinical history illustrates the difficulties generated by a case of peritoneal carcinomatosis and describes the importance of a multidisciplinary approach. When the primary origin is unknown before the initiation of treatment, the peritoneal carcinomatosis is a form of carcinoma of unknown primary (CUP). When this condition affects a woman, it becomes a particular entity with a better outcome, for which a specific first-line treatment should be initiated.

Abstract
Renal cell carcinoma accounts for 3% of all malignant tumors. Until a few years ago, immunotherapy (Interferon and/or Interleukin-2) was the only approved systemic treatment in the metastatic setting. Better knowledge of renal cell cancer biology drew attention on the fundamental role of angiogenesis. Several strategies targeting angiogenesis have been developed including VEGF and VEGFR inhibitors. They are now the standard treatment in first and second line. Pazopanib, a VEGFR tyrosine kinase inhibitor, is one of the treatment options recommended for patients with metastatic renal cell carcinoma, in first line and after cytokines failure. Since more recently, pazopanib is also approved in the treatment of metastatic soft tissue sarcoma, after failure of at least one line of chemoterapy. In this paper, we will review the mechanism of action and the clinical results of pazopanib in renal cell carcinoma and sarcoma.

Abstract
Up to 50% of cancer patients will receive radiation therapy as a part of their treatment. Radiation may be delivered with curative or palliative intent, according to the extent of disease, the patient's performance status and his wishes. The aim of palliative radiotherapy is to locally control primary tumor or metastasis and, thus, to slow down the disease. Another purpose is to decrease symptoms as part of the supportive care in the end of life. The total dose, the dose per fraction and the technique of irradiation used vary with the treatment aim. Indications of radiotherapy in the end of life are reviewed in this paper

Bone is one of the most common sites of metastases from cancer. Most anticancer treatments are highly toxic but only a fraction of all patients respond to them. Guidelines are needed to evaluate the response in the routine practice of oncology as well as in clinical trials in which new treatment options are evaluated. All current imaging procedures have major limitations. This article reviews old and new criteria for response evaluation. The major problem of accurate response evaluation in bone disease is discussed in detail. Some examples from our daily practice illustrate the difficulties.

Abstract
In western countries, every woman out of eight will develop breast cancer. Over the last two decades, the incidence has considerably increased, but mortality has remained stable and begins to decrease in Europe and the United-States, probably because of new therapy, changes in the use of hormone replacement therapy in postmenopausal women and early diagnosis. Breast cancer is still the first cause of death by cancer in woman under 65. "Triple negative" a breast cancer, a subtype representing 10% of all breast cancers, is characterised by the absence of receptors to oestrogen, progesterone and no histochemical expression of HER-2 growth factor. This subtype carries a poor prognosis and a high incidence of early metastatic recurrence. Furthermore, no target therapy can be defined up to now in this subtype. Thus, identification of new target therapy and prediction of tumoral response to various treatments could help in the global understanding of patients affected by this particularly aggressive type of breast cancer.

Abstract
The Stewart-Treves Syndrome is defined as an angiosarcoma (very aggressive malignant tumor originating from endothelial cells) appearing in a specific clinical setting. This tumor develops in patients suffering from chronic lymphedema of the upper limb following mastectomy and axillary lymph node dissection for breast cancer. The diagnosis relies on medical history, clinical examination and a histological assesment (biopsy or resection). This syndrome represents a rare clinical entity. Unfortunately, the prognosis is poor. A large surgical resection is the treatment of choice if the patient is a candidate for a surgical resection with a curative intent Radiotherapy is sometimes used as a palliative local treatment. Chemotherapy is only used in more advanced cases, not curable by surgery alone.

Abstract
About 9,500 new breast cancers are diagnosed in Belgium every year. Improvement of our knowledge of altered molecular events leading to the proliferation of tumor cells has resulted in the development of targeted therapies in subgroups of cancers. One of the first validation of targeted therapy is the anti-HER-2 monoclonal antibody trastuzumab (Herceptin) in patients with overexpression of human epidermal growth factor receptor type 2 (HER2) occurring in 20 to 25% of invasive breast carcinoma. Trastuzumab binds the extracellular juxtamembrane domain and is only active in tumor with HER2 gene amplification detected by fluorescence in situ hybridization (FISH). The results from randomized trials have rapidly lead to the approvement of the drug in the metastatic and then in the adjuvant setting. Another targeted therapy, also approved in the treatment of breast cancer, is the monoclonal antibody bevacizumab with an anti-VEGF (Vascular Endothelial Growth Factor) activity. We will review the benefit of these targeted therapies in breast cancer and their role in the treatment of breast cancer.

Abstract
For many years, chemotherapy, hormonotherapy and immunotherapy were the mainstay of cancer treatment. Recent advances in our knowledge of cell biology and particularly of cancer cell transformation, growth and metastasis have led to the identification of specific pathways playing a role in the pathophysiology of cancer. New drugs specifically developed to control these targets are collectively named "targeted therapies". Two types of targeted therapies are available: kinase (mainly tyrosine kinase) inhibitors (suffix -nib) are small molecules binding directly to the intracellular kinase domain and acting as competitive inhibitor of ATP binding and monoclonal antibodies (suffix -mab) directed towards specific cell surface receptors or their ligands to prevent receptor activation. This paper will only review monoclonal antibodies (mabs). Thirty years after their discovery mAbs have become efficient therapeutic tools. Progress in molecular engineering as well as improved knowledge of cell signalling pathways together with a better selection of the targets turned them into valuable treatments. Several mAbs are currently licensed for the treatment of hematological or solid malignancies and many others are expected in the near future.

Abstract
Radiation recall dermatitis is an inflammatory skin reaction occurring in a previously irradiated field following the delivery of a promoting agent. It has been described after a number of antineoplastic agents such as gemcitabine, taxanes, anthracyclines. We report the case of a 50-year-old man with metastatic prostate cancer who developed two consecutive radiation recall dermatitis episodes triggered by oral cyclophosphamide. They occurred 4 to 5 weeks after palliative radiotherapy on bone metastasis. Spontaneous resolution was observed within 6 weeks after discontinuation of cyclophosphamide and with local supportive care. To our knowledge this is the first reported case of radiation recall dermatitis after oral cyclophosphamide.

Abstract
Epithelial ovarian cancer is frequently diagnosed at advanced-stage disease and chemotherapy is nearly always required. Optimally debulked patients may need adjuvant chemotherapy while, most of the time this chemotherapy will be given to those with advanced-stage disease. Also relapses will be treated differently whether they occur early or late in the course of the disease. This paper reviews medical treatment modalities according to stage based on published data. Maintenance and consolidation treatments are also discussed. Finally a brief insight into new therapeutic tools is also given.

Abstract
Over the last decades, significant advances were make in basic research as concerns the malignant transformation of normal cells. As a result, new targets for treatment were identified. "Targeted therapies" indicates that treatments are directed against specific molecular targets that play a major role in the activation of cell division and in the growth and dissemination of tumors. In particular, targeted therapies were developed against epithelial growth factor receptors and angiogenesis. We can expect specifise therapies against many other targets in the near future. Several drugs have obtained a marketing license. Predictive factors for tumor response and long term outcome should be developed for a better selection of the patient population who will benefit from these treatments. New imaging techniques are under development in order to assess the molecular response to these new approaches.

[Targeted therapies in breast cancer: current status and perspectives]. REVUE MEDICALE DE LIEGE 2007; 62 Spec No:2-5. [PMID: 18214352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/25/2023]
Abstract
The introduction of targeted therapies has largely modified the treatment strategies in oncology. Two targets are currently used for defining the systemic treatment of breast cancer: hormone receptors and HER2 overexpression. Trastuzumab, a monoclonal antibody, is the only registered antiHER2 treatment in Belgium. The association of trastuzumab with chemotherapy is now the recommended adjuvant treatment for early breast cancer overexpressing HER2. Other antiHER2 medications are available and some will probably be registered soon. Angiogenesis is another potential target for improving the treatment results. The CHU Liège, as a reference center for the systemic treatment of solid tumors, participates in many international trials in order to validate these new approaches. The highest quality of care is required to be in compliance with the conduct of these clinical trials. Another benefit for the patient is the easy access to last generation medical treatments, generally not accessible in our health care system in Belgium outside of clinical trials.

Insulin-Like Growth Factor (IGF) family and prostate cancer. Crit Rev Oncol Hematol 2006; 58:124-45. [PMID: 16387509 DOI: 10.1016/j.critrevonc.2005.10.003] [Citation(s) in RCA: 102] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2005] [Revised: 09/30/2005] [Accepted: 10/07/2005] [Indexed: 11/28/2022] Open
Abstract
There is abundant in vitro, animal and epidemiologic evidence to suggest that the Insulin-Like Growth Factor (IGF) family is a multi-component network of molecules which is involved in the regulation of both physiological and pathological growth processes in prostate. The IGF family plays a key role in cellular metabolism, differentiation, proliferation, transformation and apoptosis, during normal development and malignant growth. This family also seem essential in prostate cancer bone metastases, angiogenesis and androgen-independent progression. Therapeutic alternatives in men with progressive prostate cancer after androgen ablation are very limited. More effective therapies are needed for these patients. Pharmacologic interventions targeting the IGF family are being devised. Such strategies include reduction of IGF-I levels (growth hormone-releasing hormone antagonists, somatostatin analogs), reduction of functional IGF-I receptor levels (antisense oligonucleotides, small interfering RNA), inhibition of IGF-IR and its signalling (monoclonal antibodies, small-molecule tyrosine kinase inhibitors) and Insulin-Like Growth Factor Binding Proteins.

Abstract
We report a patient with multiple myeloma who suffered from hyperammonemia after a second stem cell autograft. This syndrome is not well known but is associated with a high mortality rate. Considering the possibility of this diagnosis in patients developing confusion and neurological degradation with respiratory alkalosis after intensive chemotherapy, could allow earlier treatment and perhaps improved survival. Possible mechanisms and potential therapies are discussed. With rapid recognition and treatment of the syndrome, the patient fully recovered. One and a half years later, she is still alive and well, on interferon for persisting myeloma.
