Impact of modern systemic therapies and clinical markers on treatment outcome for metastatic melanoma in a real-world setting.

BACKGROUND: The survival in metastatic melanoma has dramatically improved after the introduction of immune checkpoint- (ICIs) and MAPKinase inhibitors (MAPKis). OBJECTIVE: Our aim was to describe therapy response and survival in a real-world population as well as to assess the associations between clinical variables and therapy outcome for patients with metastatic melanoma receiving first-line ICIs or MAPKis. METHODS: A total of 252 patients with metastatic (stage IV) melanoma were prospectively followed between 1 January 2010 and 3 December 2017 with follow-up until 31 March 2019, at the Karolinska University Hospital, Sweden. Hazard ratios (HRs) for progression-free survival (PFS) and overall survival (OS) were analysed with Cox regression, and logistic regression was used to estimate odds ratios (ORs) for therapy response. RESULTS: Patients receiving ICIs (n = 138) experienced longer PFS compared to patients that received MAPKis (n = 114; median PFS for ICIs was 6.8 months, and median PFS for MAPKis was 5.3 months). In the multivariable analyses of clinical markers, increasing M-stage (OR 0.65; 95% CI 0.45-0.94; P = 0.022) and male sex (OR 0.41; 95% CI 0.19-0.90; P = 0.027) were significantly associated with lower response to ICIs. Lower baseline albumin levels (OR 0.90; 95% CI 0.83-0.98; P = 0.019) and male sex (OR 0.33; 95% CI 0.12-0.93; P = 0.036) were related with lower response to MAPKis. For ICIs, increasing M-stage (HR 1.34; 95% CI 1.07-1.68; P = 0.010), increasing LDH (HR 1.73; 95% CI 1.19-2.50; P = 0.004) and decreasing albumin (HR 1.06; 95% CI 1.01-1.10; P = 0.011) were significantly associated lower PFS in the adjusted model. The corresponding markers for MAPKis were increasing LDH (HR 1.44; 95% CI 1.08-1.92; P = 0.013) and decreasing albumin (HR 1.05; 95% CI 1.02-1.09; P = 0.005) for PFS. CONCLUSION: ICIs and MAPKis were effective in this real-world population, and we could confirm the importance of previously reported clinical prognostic markers. Albumin values may be associated with therapy outcome but need further validation.

[Radiofrequency ablation for palliation of soft tissue tumor pain]. / La radiofréquence dans le traitement palliatif à visée antalgique des tumeurs des parties molles.

PURPOSE: To assess the efficacy of radiofrequency (RF) ablation for palliation of soft tissue tumor pain. MATERIALS AND METHODS: Retrospective study of 12 patients receiving palliative treatment for soft tissue tumors (5 primary tumors including 4 sarcomas and 1 PEComa and 7 metastatic tumors) with pain refractory to standard management. RF ablation was performed under CT or ultrasound guidance. RESULTS: The efficacy was determined by using pain scores and treatment regimen modifications after RF ablation. Response was graded as absent, partial or complete. Short term symptomatic relief was observed in 100% of cases, with complete response in 43% of cases ; Mid term and long term symptomatic relief was observed in 70% and 83% of cases respectively. We also observed dosage reduction for narcotics with corresponding reduction in related side-effects and functional improvement in some patients. A single case of complication with serosanguinous collection within a region of necrosis was observed. CONCLUSION: Radiofrequency ablation for palliation of soft tissue tumor pain may be a useful complement to standard management. It results in symptomatic improvement with few complications.

Efficacy of lenograstim on hematologic tolerance to MAID chemotherapy in patients with advanced soft tissue sarcoma and consequences on treatment dose-intensity.

PURPOSE: This two-arm, double-blind, randomized trial was conducted to determine the effects of lenograstim, a glycosylated recombinant human granulocyte colony-stimulating factor (rHu-G-CSF), on the hematologic tolerance of patients with sarcoma treated with mesna, doxorubicin, ifosfamide, and doxorubicin (MAID) chemotherapy. PATIENTS AND METHODS: Forty-eight patients with metastatic or locally advanced soft tissue sarcoma were, following the first cycle of a combination with doxorubicin 60 mg/m2, ifosfamide 7.5 g/m2, and dacarbazine 900 mg/m2, ifosfamide 7.5 g/m2, and dacarbazine 900 mg/m2 given on days 1 to 3, randomized to receive either lenograstim 5 micrograms/kg/d by once-daily injection from day 4 to day 13, or its vehicle. For subsequent cycles, 28 patients continued on the same chemotherapy and lenograstim was systematically given as prophylactic treatment in an open manner. RESULTS: Following the first cycle of MAID, the duration of neutropenia was reduced in patients who received lenograstim as compared with those who received placebo, with a median duration of neutropenia ( < 0.5 x 10(9)/L neutrophils) of 0 days (range, 0 to 3) and 5 days (range, 0 to 10), respectively (P < .001). All patients who received lenograstim had recovered at least 1 x 10(9)/L neutrophils (polymorphonuclear lymphocytes [PMN]) on day 14, compared with only one of 26 in the placebo group (P < .001). The median time to recover this neutrophil level was 12 days (range, 10 to 13) and 17 days (range, 14 to 21), respectively (P < .001). Neutropenic fever occurred in five (23%) and 15 (58%) patients respectively (P = .02). Twenty-eight patients received at least two cycles (median, four) of MAID at the same dose. Toxicity remained constant across all treatment cycles. A progressive increase in thrombocytopenia was noted, with median platelet nadirs of 102 x 10(9)/L at cycle 2 and 19.5 x 10(9)/L at cycle 6, but did not result in significant treatment modifications. Consequently, median relative dose-intensities remained greater than 0.95 for up to six consecutive MAID cycles. CONCLUSION: Lenograstim significantly improved hematologic tolerance in patients treated with the MAID chemotherapy regimen and, therefore, allowed optimal adhesion to the theoretic doses planned for up to six cycles. Whether such an optimization in relative dose-intensity will result in an improvement of treatment efficacy remains to be determined.

Docetaxel is a major cytotoxic drug for the treatment of advanced breast cancer: a phase II trial of the Clinical Screening Cooperative Group of the European Organization for Research and Treatment of Cancer.

PURPOSE: This trial investigated the toxicity and efficacy of docetaxel as first-line chemotherapy in women with heavily pretreated advanced breast cancer. PATIENTS AND METHODS: From April 1992 to August 1992, 35 patients with advanced breast cancer from 29 to 65 years of age with a performance status of 0 to 2 were entered onto the study. Docetaxel 100 mg/m2 was administered every 3 weeks as a 1-hour infusion on day 1 without routine premedication for hypersensitivity reactions. Thirty-one patients were assessable for response. Previous adjuvant chemotherapy had been given to 11 patients. RESULTS: Five complete responses (CRs) and 16 partial responses (PRs) were observed, for an overall response rate of 67.7% (95% confidence interval, 49% to 83%). A CR occurred at 13 of 45 assessable sites (four liver, two lung, three breast, three lymph node, and one skin). The median duration of response was 44+ weeks, the median time to disease progression 37+ weeks, and the median overall survival time 16+ months. Among 34 patients assessable for toxicity (177 cycles; median, five cycles per patient), the following side effects were reported: nadir neutropenia grade 3 (three patients); grade 4 (31 patients); no grade 3 to 4 infection, acute hypersensitivity-like reaction (10 patients); grade 2 to 3 alopecia (all patients); and grade 2 to 3 nausea and vomiting (six patients). Fluid retention occurred in 26 patients and consisted of weight gain, edema alone (15 patients), or edema associated with serous effusion (11 patients). This side effect led to treatment discontinuation in 16 of 21 responding patients after a median of five cycles and a median cumulative dose of docetaxel of 574 mg/m2. CONCLUSION: Our data suggest that docetaxel has major antitumor activity when used as a single cytotoxic agent as first-line chemotherapy in advanced breast cancer.

Outpatient treatment with subcutaneous interleukin-2 and interferon alfa administration in combination with fluorouracil in patients with metastatic renal cell carcinoma: results of a sequential nonrandomized phase II study. Subcutaneous Administration Propeukin Program Cooperative Group.

PURPOSE: We report the results of the Subcutaneous Administration Propeukin Program (SCAPP) II trial of an outpatient treatment in renal cell carcinoma using interleukin-2 (IL-2) and interferon alfa-2a (IFN-alpha) administered subcutaneously in combination with fluorouracil (5-FU). The objective of this multicenter trial was to confirm that the combination of IL-2, IFN-alpha, and 5-FU leads to a response rate greater than 20%. PATIENTS AND METHODS: Patients with metastatic renal cell carcinoma were included in this study. During the induction phase of the treatment, which lasted 10 weeks, IL-2 and IFN-alpha were administered subcutaneously three times a week for 8 weeks at doses of 18 MIU and 9 MIU, respectively. During these 8 weeks, every Monday, 5-FU was administered at a dose of 750 mg by intravenous infusion over 30 minutes. After evaluation, responding patients or patients with stable disease (SD) were given maintenance treatment, until disease progression (PD) or the appearance of unacceptable toxicity. Each maintenance cycle consisted of a 2-week treatment followed by a three-week rest period. During treatment, IL-2 and IFN-alpha were administered subcutaneously three times a week at doses of 18 MIU and 9 MIU, respectively. Every Monday, 5-FU was administered at a dose of 750 mg by intravenous infusion over 30 minutes. RESULTS: This trial was closed when the sixth sequential analysis showed the lack of benefit from this combination. At the end of the induction period, of 62 patients, 12 (19%; 95% confidence interval [CI], 10% to 31%) reached an objective response, including one complete response (CR), 16 presented with SD, and 27 showed PD. Twenty-seven patients (43%) developed severe toxicity that required reduction of the planned doses (13 patients), delayed treatment (eight patients), or treatment termination (six patients). Seventeen patients were given maintenance treatment. One- and 2-year survival rates were estimated at 55% and 33%, respectively. The 2-year survival rate was 15% in 11 patients who presented with three poor-prognosis factors and 41% in 51 patients who initially presented with no, one, or two poor-prognosis factors (P = .04). CONCLUSION: As in other recently published studies that used 5-FU, IL-2, and IFN-alpha, the multicenter SCAPP II trial in patients with metastatic renal cell carcinoma generated severe toxicity. This sequential trial failed to confirm the favorable results previously obtained by Atzpodien and Sella with this combination of three drugs. Its efficacy, assessed on the response and survival rates, is near to the results observed in programs that used IL-2 alone given subcutaneously.

Phase II study of cystemustine in metastatic colorectal carcinoma. A trial of the EORTC Clinical Screening Group.

27 patients with metastatic colorectal carcinoma were treated, every 2 weeks, with 60 mg/m2 cystemustine, a new chloro-2-ethyl nitrosourea derivative. Haematological toxicity was the major side-effect including neutropenia and thrombocytopenia. We did not observe any complete or partial response. Cystemustine, with this dose and this schedule, has no activity in colorectal cancer.

Results of a phase II trial with second-line cystemustine at 60 mg/m2 in advanced soft tissue sarcoma: a trial of the EORTC Early Clinical Studies Group.

The aim of this phase II trial was to examine the efficacy of a new nitrosourea, cystemustine, in soft tissue sarcoma. Between January 1990 and March 1991, 32 pretreated patients with advanced soft tissue sarcoma were enrolled. Cystemustine was given every 2 weeks at 60 mg/m2 via a 15-min i.v. infusion. All eligible patients were considered evaluable for response and toxicity (WHO criteria). Of the 32 enrolled patients, 4 were ineligible, leaving 28 evaluable patients. All but 1 had been pretreated: 6 with adjuvant chemotherapy, 18 patients with first-line palliative chemotherapy without nitrosourea, 3 with both treatments, and 18 had received radiotherapy. Median age was 54 years (range 20-73) and median performance status was 1 (0-2). One partial response (PR, duration 12 weeks), 2 stable disease and 25 progressions were observed, giving an overall response rate of 3.57% (confidence interval: 0.1-18.4%). Toxicity was mild, and was mainly neutropenia (no grade 3 or 4), thrombocytopenia (3.57% grade 3 and grade 4) and nausea-vomiting (no grade 3 or 4). It should be noted that the treatment for the patient who obtained a PR was third line with no previous response. Cystemustine with this schedule appears to have a low clinical activity and toxicity in advanced soft tissue sarcoma.

Phase I-II trial of intensification of the MAID regimen with support of lenograstim (rHuG-CSF) in patients with advanced soft-tissue sarcoma (STS).

This study was conducted to determine the maximum tolerated dose of an intensified MAID (mesna, adriamycin, ifosfamide, dacarbazine) regimen with the support of lenograstim in patients with advanced soft tissue sarcomas. Following 1 cycle of MAID at the standard dose, four patients were to be treated at each of five dosage levels: +25%, +45%, +65%, +85%, +100%. Sixteen patients were treated. Because there were no significant differences in hematologic toxicity between patients receiving lenograstim 5 or 10 microg/kg/day (levels 1-5 and 1-10), the data were pooled for comparison with level 2. The median duration of absolute neutrophil count < 0.5 x 10(9)/l was 3 days at level 1 and 7 days at level 2 (p < 0.01). The median platelet nadir was 25 x 10(9)/l at level 1 and 10 x 10(9)/l at level 2 (p < 0.01). The median duration of toxicity-related hospitalization was 3.5 days and 11 days at levels 1 and 2, respectively, (p < 0.001). Mucositis > or = grade III occurred after 3/29 cycles at level 1 and 10/15 cycles at level 2 (p < 0.001). After 4 cycles at level 1, 8/8 patients still had performance status scores < or = 2, and only 4/8 had performance status scores < or = 2 after the second cycle at level 2. Lenograstim enabled an increase of 25% of the MAID regimen. At higher dose levels, severe mucositis and deterioration in performance status were dose limiting.

[Coordinated organization of symptoms management and support in all the stages of cancer disease: putting in place pluridisciplinary structures of supportive oncological care]. / Organisation coordonnée de la prise en charge des symptômes et du soutien à toutes les phases de la maladie cancéreuse: vers la mise en place de structures pluridisciplinaires de soins oncologiques de support.

The organization of the management of pain and other symptoms all along the cancer disease, of psychological support and palliative care is a complex question that does not correspond to any perfectly established model, both in France and abroad. Different structures are implied in there care and coexist with an insufficient coordination: cancerology structures, structures of chronic pain management, structures of psycho-oncology, structures of palliative care. Some other assistances are more or less isolated inside the hospital: nutritional support, social assistance, action against tobacco and other addictions, volunteer work. Because of the evolution of practices and mentalities over the last ten years, the highlights of evident interfaces and complementary activities, the notions of "continuous care" and "integrated care" inside conventional departments, the budgetary and organizational restraints, it is now possible to propose a model of hospital structure adapted to the problem of supportive care. The creation is proposed from preexisting structures, consultations, units, departments of supportive oncological care according to the size of the institution. The structure should comply with some specifications, sometimes regulations, and to coordinate at best different competencies in the interest of the patients and medical teams : pain and symptoms management (of which palliative care is an important part), psycho-oncology, rehabilitation (functional rehabilitation, nutrition, social work, fights against addictions). A pooling of technology settings is one of its interest. The model can be applied in other domains than cancerology and in most health institutions.

[Plasma pharmacokinetics of morphine and morphine-6-glucuronide using high performance liquid chromatography and colorimetric detection]. / Pharmacocinétique plasmatique de la morphine et de la morphine-6-glucuronide par chromatographie liquide haute performance (HPLC) avec détection coulométrique.

This pilot study was undertaken in a group of 7 patients receiving morphine either by oral route under a controlled release form (Moscontin tablets), or by subcutaneous route with continuous infusion. Complete pharmacokinetics over 24 h were carried out with blood samples taken every hour. The measurements of morphine and of its metabolite, morphine-6-glucuronide (M6G) were performed by high-performance liquid chromatography (HPLC) with coulometric detection, using nalorphine (NAL) as an internal standard. The morphinics were extracted on a Bond Elut C18 column according to a double liquid-solid extraction. The extract was chromatographed by ion-pairing on a mu Bondapak C18 column, 10 microns (300 x 3.9 mm). The minimal detectable concentrations were respectively 1 and 5 ng/ml for M and M6G. When Moscontin was given at dosages < 1 mg/kg/d, the areas under the curve over 24 h (AUC 24 h) of M were rather close to those of M6G (ratio 1.1 +/- 0.1). However, with dosages > 1 mg/kg/d, a difference appeared and gradually rose to a M/M6G ratio of 1.3 +/- 0.04. With subcutaneous infusion, the plasma levels of M6G were from 2 to 17-fold lower than those of M.

[Long term continuous combination of cisplatin and 5 fluorouracil in advanced breast neoplasms. A retrospective study of 77 patients]. / Association cisplatine et 5-fluorouracile continu à long terme dans les cancers du sein avancés. Etude rétrospective de 77 patientes.

Seventy-seven pre-treated patients with advanced breast cancer were administered a combination chemotherapy with cisplatin 50 mg/sqm d1, 5-fluorouracil 300 mg/sqm/d protracted continuous infusion d1-d28, allopurinol 600 mg/d po d1-d28, q29d. Overall response rate was 26%, median survival time 46 weeks, survival rate 43.3% at 1 year, 20.2% at 2 years, 10.6% at 3 years. Response rate was rather high in CNS and meningeal involvement (6/10).

[Predictive value of the hemogram for myelotoxicity induced by the association of carboplatin-fluorouracil on the 4th day of the therapeutic regimen]. / Valeur prédictive de l'hémogramme du 4e jour pour la myélotoxicité induite par l'association carboplatine-5-fluorouracile.

The aim of this study was to determine the value of haematological counts at the 4th day of a chemotherapy cycle, in order to foresee neutro and/or thrombocytopenia during the same chemotherapy cycle. One hundred and ten cycles of chemotherapeutic regimens with carboplatin (400 mg/m2, dl) and 5-fluorouracile (1 g/m2/d, by iv continuous infusion for 96 hours) every 3 weeks, were analyzed for 42 patients with locally advanced but non metastatic squamous cell carcinoma of head and neck, without prior chemotherapy. Lymphocyte counts were significantly decreased at the 4th day but normalized at the 8th day (P < 10(-6)). Decreases of lymphocyte and neutrophil counts at the 4th day were significantly correlated to grade > 2 neutropenia. The positive predictive value of lymphocyte or neutrophil counts is about 50% for some cut-off values but not high enough, with the schedule of chemotherapy in our study, to justify the systematic prophylactic therapy with haematopoietic growth factors.

[Randomized placebo trial of myeloprotection with goralatide in patients with squamous cell carcinoma of the upper respiratory and digestive tracts or esophagus, treated with a carboplatin-fluorouracil combination]. / Essai randomisé avec placebo de myéloprotection par le goralatide des patients présentant un carcinome épidermoïde des voies aérodigestives supérieures ou de l'oesophage, traités par l'association carboplatine-5 fluorouracile.

Eighty-four patients with locally advanced, non metastatic squamous cell carcinoma of head and neck or esophagus, were included in a multicentric double-blind randomized trial, comparing goralatide (12.5 or 62.5 micrograms/kg/day, d1-d4) to placebo, associated with carboplatin (400 mg/m2, d1) and 5-fluorouracile (1 g/m2/d continuous IV over 96 hours). Haematological toxicity was analysed on 221 cycles of chemotherapy. All but one patient were evaluable because of early death without haematological toxicity. No significant difference was observed for mean nadir of leukocytes, granulocytes, platelets counts and hemoglobin level. Duration of haematological toxicity was no significantly different for the two groups of patients. Anemia and lymphopenia were more frequent in the goralatide treated patients. Clinical and biological tolerability of goralatide was excellent.

[MRI aspect of hepatic adenomatosis]. / Aspect IRM d'une adénomatose hépatique.

We report a case of hepatic adenomatosis demonstrated with MR imaging. The diagnosis can be suspected when this technique shows multiple hepatic lesions which present an iso-signal intensity on T1-wi, a hyperintense signal on T2-wi and rapid wash-in and wash-out of gadolinium. Injection of superparamagnetic iron oxide mag be useful in the characterization of the lesion: a decreased signal intensity after injection rules out the diagnosis of metastasis. Because of the unknown course of hepatic adenomatosis, histological proof and radiological follow-up are recommended.

[Surgical treatment of metastases of the humerus]. / Traitement chirurgical des métastases de l'humérus.

Surgical treatment of metastasis disease of the humerus was applied for 46 lesions among 42 patients, i-e 22% of overall osteosyntheses for skeletal metastasis. Two patients only are still alive at 3 and 4 years. The mean survival time is 8.1 months and at 3 months 50% died. Metastasis disease of the humerus becomes evident late during the evolution of the primary cancer, but 26% are revealing lesions. For 9.5% the primary tumor remains unknown. After review of the surgical methods generally used, indirect osteosynthesis by intra-medullary pinning according to Hackethal, without bone cement, is alleged. So the arm is immediately mobilized and a complementary irradiation is applied in post-operative. Prophylactic fixation of impending fractures is encouraged in order to suppress pain, and for better function. This paper demonstrates the changing concept of internal fixation of pathologic fractures and recommends intra-medullary nailing or pinning.

Supportive care organisation in France: an in depth study by the French speaking association for supportive care in cancer (AFSOS).

BACKGROUND: Supportive care in cancer (SCC) was further enhanced in the Second National Cancer Act decreed in December 2009. The aim of our study was to assess current SCC efficacy. PATIENTS AND METHODS: The French speaking association for supportive care in cancer (AFSOS) conducted an observational study to evaluate practices, organisations and information given to patients. A specific 32 point questionnaire was sent to 1621 French physicians (MDs) caring for cancer patients. RESULTS: Three different organisations were evaluated: the individual MDs, the transversal team and its particular structure specialised in global patient care specifically developed at comprehensive cancer centres - CCC. During their disease, 68% of patients received SCC, which was more available during the palliative period (90%) than at the diagnosis (44%). Our results found that 71% of cancer departments had a specific interdisciplinary cross-team to provide SCC, particularly in CCC (62%; p=0.01) while 37% had specific inpatient units. A specific organisation dedicated to home care was greater in CCC than in public or private centres (69%, 45%, 20% respectively; p=0.01). Adverse event information was performed more by an oncologist than other specialists (p=0.01). CONCLUSION: Our results suggest that the specific SCC organisation could be a useful management tool to improve supportive care for cancer patients.

[Practice guidelines of the use of bisphosphonates in solid tumours with bone metastases and in multiple myeloma]. / Guide de recommandations d'utilisation des bisphosphonates dans les lésions osseuses malignes des tumeurs solides et du myélome multiple.

Bisphosphonates are indicated for the treatment of bone lesions in patients with solid tumours or multiple myeloma. Bisphosphonates have proven their effectiveness in reducing the number of bone complications (hypercalcemia, pain, disease-related fractures, spinal cord compression) and delaying their occurrence in patients with bone tumours; they have also been shown to reduce the need for bone surgery and palliative or pain-relieving radiotherapy in these patients. International recommendations for the treatment of bone lesions related to malignant solid tumours and multiple myeloma have been established. We have elaborated clinical practice guidelines on the use of bisphosphonates to assist treatment decision-making in bone oncology. The guide contains decision trees and tables with information to guide pre-treatment evaluation and patient follow-up, as well as indications and conditions of use of bisphosphonates. In 2007, the regional cancer network of Rhône-Alpes, ONCORA, formed a working group (GIP ONCORA) to elaborate the guideline. The final version was then discussed and adopted at a plenary session in July 2009, during a collaborative workshop on supportive care recommendations organized by ONCORA and the regional cancer network of Lorraine.

[Initial management in oncology: results of CPRIM surveys on 2,583 patient's perceptions and expectations (outside Anticancer Centers)]. / Prise en charge initiale: résultats des enquêtes CPRIM sur le ressenti et les attentes de 2,583 patients (hors centres de lutte contre le cancer).

During the initial phase of management, the caregivers' role is particularly difficult. These two consecutive surveys have been conducted to cover three main aspects: 1) How the initial management took place; 2) What the perceived deficits were; 3) What improvements could be made. A self administered and anonymous questionnaire was given to the patients by physicians. Surveys were conducted in numerous institutions representative of all kinds of practice except for Anticancer Centres. Two thousand five hundred and eighty three adult patients have completed the questionnaire (1366 and 1217 respectively in the first and subsequent survey): women (55%), age under 70 years (76%), breast cancer (32%). Results were rather encouraging. About sixty per cent of the patients are entirely satisfied by the given information and 95% are confident with the department of care. The mean level of global aid is 8.2/10 in the first survey and 8.6/10 in the second one. However, improvements remain needed, particularly for the 8% dissatisfied patients. In spite of the classical bias for these studies, this work gives several concrete responses for improving initial management, particularly for the first consultation in the centre, which has a major impact on the patient satisfaction.
