Palliative care integration and end-of-life care intensity for patients with NSCLC.

BACKGROUND: Non-small cell lung cancer (NSCLC) without oncogenic driver mutations is considered to have a poor prognosis, although recent therapeutic progress. This study aims to assess the real-life integration of palliative care (PC) and the intensity of end-of-life (EOL) care for this population. METHODS: This was an observational cohort study of decedent patients from metastatic NSCLC without oncogenic driver mutations over the period 01/2018 to 12/2022, treated in first line with immunotherapy +/- chemotherapy. We analysed PC integration and aggressiveness criteria of EOL care in the last month before death: systemic anti-cancer treatment administration, emergency room visits, intensive care unit admission, hospitalization, hospitalization duration > 14 days, and hospital death. RESULTS: Among 149 patients, 75 (50 %) met the PC team at least once, and the median time from the first encounter to death was 2.3 months. In the last month before death, at least one criterion of aggressive EOL care was present for 97 patients (70 %). For patients with PC use < 30 days and for patients with PC use < 90 days before death, there were significant changes: increase in the frequency of systemic anti-cancer treatment (respectively 51.1 % vs 20 %; p < 0.001 and 58.7 % vs 6.2 %; p < 0.001); decrease in hospitalization lasting > 14 days (respectively 30 % vs 7 %; p = 0.001 and 36 % vs 6.2 %; p = 0.018) and in death hospitalisation (respectively 66 % and 18 %; p < 0.001 and 58.7 % and 10.3 %; p < 0.001). After adjusting for the factors tested, patients with no PC or late PC use in the last month before death or in the last three month before death, the odds ratio (OR) remained significantly greater than 1 (respectively OR = 3.97 [1.70; 9.98]; p = 0.001 and OR = 23.1 [5.21-177.0], p < 0.0001). CONCLUSION: PC is still insufficiently integrated for patients with NSCL cancer. Cancer centres should monitor key indicators such as PC use and aggressiveness criteria of EOL care.

Could palliative sedation be seen as unnamed euthanasia?: a survey among healthcare professionals in oncology.

BACKGROUND: In 2016 a French law created a new right for end-of-life patients: deep and continuous sedation maintained until death, with discontinuation of all treatments sustaining life such as artificial nutrition and hydration. It was totally unprecedented that nutrition and hydration were explicitly defined in France as sustaining life treatments, and remains a specificity of this law. End- of-life practices raise ethical and practical issues, especially in Europe actually. We aimed to know how oncology professionals deal with the law, their opinion and experience and their perception. METHODS: Online mono-centric survey with closed-ended and open-ended questions in a Cancer Comprehensive Centre was elaborated. It was built during workshops of the ethics committee of the Institute, whose president is an oncologist with a doctoral degree in medical ethics. 58 oncologists and 121 nurses-all professionals of oncological departments -, received it, three times, as mail, with an information letter. RESULTS: 63/ 179 professionals answered the questionnaire (35%). Conducting end-of-life discussions and advanced care planning were reported by 46/63 professionals. In the last three months, 18 doctors and 7 nurses faced a request for a deep and continuous sedation maintained until death, in response to physical or existential refractory suffering. Artificial nutrition and even more hydration were not uniformly considered as treatment. Evaluation of the prognosis, crucial to decide a deep and continuous sedation maintained until death, appears to be very difficult and various, between hours and few weeks. Half of respondents were concerned that this practice could lead to or hide euthanasia practices, whereas for the other half, this new law formalised practices necessary for the quality of palliative care at the end-of-life. CONCLUSION: Most respondents support the implementation of deep and continuous sedation maintained until death in routine end-of-life care. Nevertheless, difficulty to stop hydration, confusion with euthanasia practices, ethical debates it provokes and the risk of misunderstanding within teams and with families are significant. This is certainly shared by other teams. This could lead to a multi-centric survey and if confirmed might be reported to the legislator.

Circulating tumor cell thresholds and survival scores in advanced metastatic breast cancer: the observational step of the CirCe01 phase III trial.

The clinical validity of circulating tumor cell (CTC) count changes during chemotherapy in metastatic breast cancer patients has been validated, but its clinical utility remains to be demonstrated. We report here the non-randomized run-in phase of the CirCe01 trial which was designed to evaluate CTC changes and thresholds to other palliative prognostic scores and establish CTC thresholds to be used in the randomized part of the study. CTC count (CellSearch®) and other prognostic parameters (serum albumin level, lymphocyte level, LDH level, prognostic inflammatory and nutritional index (PINI) and Barbot's score) were assessed in 56 metastatic breast cancer patients before the first cycle of third line chemotherapy. Early changes of CTC count were correlated with treatment outcome. Independent prognostic markers in multivariate analysis were: low serum albumin (HR = 11.1), poor performance status (HR = 3.8), ≥5 CTC/7.5 ml (HR = 3.8) and triple negative subtype (HER2+ and hormone positive vs triple negative: both HR = 0.2). Among patients with ≥5 CTC/7.5 ml at baseline, a composite criteria (<5 CTC/7.5 ml or relative decrease ≥-70% of the baseline CTC count) showed better prognostication for PFS (p=0.002).

[How to improve cancer patients' satisfaction with medical information]. / Comment améliorer la satisfaction des patients sur l'information médicale en cancérologie ?

The medical information becomes integrated into a communications strategy, the generally admitted model of which is centered on the patient; that is in the listening of these concerns and these values. The medical quality information is facilitated by the preliminary collection of the symptoms and the needs of the patients thanks to the questionnaires of quality of life, if they are used during the consultation to direct the discussion. Satisfactory medical information includes a discussion about the questions of the patients in terms of outcomes. Patient's individual factors can influence the need of medical information, as the age and the pathology. Patient's needs can also vary with time and according to the phase of the disease. Cultural factors are essential, in particular as regards the information about prognosis. Tools to help giving the medical information are now validated as the audio cassettes or video. Those tools can take the shape of a prompt list to help patients to ask questions. The majority preference of style of participation in the medical and therapeutic decisions and is the collaborative mode. Physician's attitude is determinant to leave the patients who wish it to have an active role, what allows them a very beneficial feeling psychologically of control over the disease. Decision-making helps are successfully sometimes elaborated to support the participation of the patients. In palliative phase, the need of medical information about prognosis associated with preservation of hope is not still understood by physicians who oscillate between saying the all or none. Honest information at the right time is the majority wish of the patients, although certain patients adopt clearly a strategy of avoidance. The medical communication requires a specific training on this subject. Talking time must be opened to the doctors to approach the relational problems which they meet. The clinical research has to continue to understand better the interactions in doctors/patients communication.

[End of chemotherapy decision for metastatic breast cancer patients.]. / La décision d'arrêt de chimiothérapie pour les patients atteints de cancer du sein métastatique.

If chemotherapy beyond the third line often gives sum clinical benefits, it is sometimes prescribed only to avoid telling bad news to patients. Palliative chemotherapy can lead to symptom reduction and greater health related quality-of-live, but longer survival is unlikely. Physician's questioning about chemotherapy continuation is an ethical duty so is the discussion with patients and caregivers about prognosis and possibility to receive principally palliative care. Medical information about prognosis must be told "step by step", following patients questioning and their capacity listening to the answers. Exhaustion of chemotherapy efficacy is the best argument to explain chemotherapy stop, which does not mean end-of-life, particularly for patients with slow growing tumour. Maintain hope for patients in regard with their medical situation is vital in a psychological way, to stay alive and to be able to project himself in the close future. Modalities of decisions taking about end of chemotherapy have to be defined but consultation of all caregivers implicated in the palliative patients care is essential.

Gemcitabine combined with oxaliplatin in advanced pancreatic adenocarcinoma: final results of a GERCOR multicenter phase II study.

PURPOSE: Based on preclinical in vitro synergy data, this study evaluated the activity and toxicity of a gemcitabine/oxaliplatin combination in patients with metastatic and locally advanced pancreatic adenocarcinoma. PATIENTS AND METHODS: Previously untreated metastatic and locally advanced unresectable pancreatic adenocarcinoma patients were enrolled onto this multicenter phase II study. Patients received gemcitabine 1,000 mg/m(2) as a 10-mg/m(2)/min infusion on day 1 and oxaliplatin 100 mg/m(2) as a 2-hour infusion on day 2 every 2 weeks. Patients with metastatic disease were treated until evidence of progressive disease, whereas patients with locally advanced disease received six cycles in the absence of progression, followed when appropriate by concomitant radiochemotherapy. RESULTS: Among 64 eligible patients included in eight centers, 30 had locally advanced and 34 had metastatic disease. Response rate for the 62 patients with measurable disease was 30.6% (95% confidence interval, 19.7% to 42.3%), 31.0% for locally advanced and 30.3% for metastatic patients. Among 58 assessable patients, 40% had clinical benefit. Median progression-free survival and median overall survival (OS) were 5.3 and 9.2 months, respectively, with 36% of patients alive at 1 year. Median OS for patients with metastatic disease and locally advanced disease were 8.7 and 11.5 months, respectively. With 574 treatment cycles (median per patient, nine; range, zero to 27), grade 3/4 toxicity per patient was 11% for neutropenia and thrombocytopenia, 14% for nausea or vomiting, 6.2% for diarrhea, and 11% for peripheral neuropathy, with no toxic deaths. CONCLUSION: Palliative effects, response rate, and survival observed with this well-tolerated gemcitabine/oxaliplatin combination deserve additional evaluation. A comparative study of combination therapy versus gemcitabine alone is ongoing.

The relationship between introduction of American society of clinical oncology guidelines and the use of colony-stimulating factors in clinical practice in a Paris university hospital.

BACKGROUND: Clinical practice guidelines are issued periodically by professional medical societies or committees to assist practitioners in clinical decision making. However, it is unclear whether such guidelines have any lasting impact on clinical practice. OBJECTIVE: The purpose of this study was to assess the impact of the American Society of Clinical Oncology (ASCO) guidelines regarding use of hematopoietic colony-stimulating factors (CSF) on cancer care in a university hospital in Paris. METHODS: The study was performed at Hjpital Tenon, an 830-bed university hospital in Paris, in 1996 and 1997, both before and after the ASCO guidelines were implemented. The guidelines were first disseminated as a continuing medical education program and then actively implemented using a CSF prescription order form summarizing the guidelines. This form had to be used during the patient consultation and was sent to the Hjpital Tenon pharmacy for CSF dispensation. Even if CSF use did not comply with the ASCO guidelines, the pharmacy filled the prescription. Seven other university hospitals in Paris, where the ASCO guidelines were not actively implemented, comprised the control group. The main outcome measure was the proportion of prescriptions in compliance with the 1996 update of the ASCO guidelines. Secondary outcome measures were the proportions of prescriptions in compliance with ASCO guidelines regarding primary prophylactic, secondary prophylactic, and therapeutic CSF administration. RESULTS: Before implementation of the ASCO guidelines, CSF use in compliance with the guidelines was 39% (41/105) at the study site and 31% (16/51) at the control sites (P > 0.05). Six months after dissemination and implementation of the guidelines, the proportion of CSF prescriptions complying with ASCO guidelines increased significantly versus baseline (P = 0.003) in the study group, to 61% (50/82). However, even after the guidelines were implemented, compliance with guidelines on primary prophylactic CSF administration did not change significantly versus before implementation in the study group (12% [5/41] before implementation vs 6% [2/33] after implementation; P > 0.05). CONCLUSIONS: The results suggest an association between the active implementation strategy (continuing medical education and CSF prescription reminder form) and physician compliance with the ASCO guidelines. Implementation of the ASCO guidelines appears to have had some impact on medical practice.

[Therapeutic intensification and autotransplantation of hematopoietic stem cells in metastatic breast cancers]. / Intensification thérapeutique et autogreffe de cellules souches hématopoïétiques dans les cancers du sein métastatiques.

The first studies on intensive chemotherapy for metastatic breast cancer conducted in the 80s were disappointing. Despite good response rates, the duration of remission was short and long-term survivals exceptional. Nevertheless, these phase I and II trials helped to develop a better understanding of the potential indications of this new therapeutic approach and apprehend its technical aspects. Over the last 5 years, considerable progress has been made in grafting techniques and hematopoietic support greatly improving the safety of the method. Notwithstanding the financial considerations involved, it must be noted that the efficacy autologous stem cell support, in terms of recurrence-free overall survival, has not yet been demonstrated although the (controversial) results of two randomized controlled trials have recently been published. In France, the PEGASE programs for the study of autologous stem cell support in breast cancer have been developed in an attempt to elucidate the question.

Tandem high-dose chemotherapy with ifosfamide, carboplatin, and teniposide with autologous bone marrow transplantation for the treatment of poor prognosis common epithelial ovarian carcinoma.

BACKGROUND: A phase I or II trial was conducted to assess the toxicity and the efficacy of a tandem high dose chemotherapy combining ifosfamide, carboplatin, and teniposide in patients with poor prognosis ovarian carcinoma. METHODS: Thirty-seven patients were scheduled to receive tandem high dose therapy combining ifosfamide 7500 to 11250 mg/m2, carboplatin 875 ot 1000 mg/m2 and teniposide 750 to 1000 mg/m2, followed by autologous bone marrow transplantation (ABMT). Eight patients were refractory to the platin-based regimen, 7 were treated in chemosensitive relapse, and 22 in partial or complete response (PR/CR) were treated. Sixty-six cycles were administered. Sixteen patients were evaluated for response. RESULTS: The overall response rate was 56% (CR rate: 12%). Toxic effects consisted of mainly renal toxicity, esophagitis, and enterocolitis. Three patients died of therapy-related complications. Since the time of ABMT, the median overall survival (OS) duration of the whole population was 18 months and the survival rate was 14% at 60 months. For the 22 patients treated after PR or CR, the median OS duration was 24 months and the survival rate was 32% at 60 months. Tandem high dose therapy with ABMT was unable to circumvent resistance to conventional chemotherapy or to prolong the duration of survival for patients treated in chemosensitive relapse. For patients treated after CR or PR, the survival results were similar to that achieved with conventional therapy. CONCLUSIONS: Prospective, randomized studies, including patients only after CR or with minimal residual disease, are urgently required to evaluate the activity of high dose therapy in the treatment of advanced ovarian carcinoma.

[High-dose therapy and hematopoietic cell autotransplantation in the treatment of adult gynecologic tumors]. / Intensification thérapeutique et autotransplantation de cellules souches hématopoïétiques dans le traitement des tumeurs gynécologiques de l'adulte.

Autologous bone marrow transplantation for the treatment of gynecologic tumors in adults remains an uncommon therapeutic approach. The feasibility of such high-dose therapies is clearly proved, especially with the advent of hematopoietic growth factors and the rescue by the peripheral stem cells to reduce the duration of the chemotherapy-induced myeloid aplasia. The question is to exactly define the place of high-dose therapy in the land of solid tumors. In the treatment of poor prognosis breast cancer, high-dose therapy with autologous bone marrow transplantation or with peripheral stem cells support is able to convert some patients with partial response into complete responders. However, the consequences on overall survival and disease-free survival are not convincing. For metastatic breast cancer and for poor-prognosis tumors (inflammatory breast cancer, axillary metastatic nodes > or = 8), the interest of high-dose therapy has to be determined by randomized studies. These studies are ongoing in USA and in France. For the treatment of poor-prognosis ovarian cancer, the situation is more difficult to appraise. Randomized studies have to be done to precisely define the interest of high-dose therapy in terms of response and disease-free survival for the treatment of ovarian carcinomas.

Phase II trial of 5-fluorouracil, leucovorin and cisplatin for treatment of advanced pancreatic adenocarcinoma.

BACKGROUND: Advanced pancreatic adenocarcinoma is a rapidly fatal disease for which an active chemotherapy regimen is sought. Here we report the outcome of a phase II trial to assess the toxicity and efficacy of a combination of 5-fluorouracil (5-FU), leucovorin and cisplatin (CDDP). METHODS: A regimen combining leucovorin (200 mg/m2/d x 5d), 5-FU (375 mg/m2/d x 5d in a 2-hour infusion) and CDDP (15 mg/m2/d x 5d) was given to 52 patients with histologically-proven, previously untreated, locally advanced (n = 13) and/or metastatic (n = 39) pancreatic adenocarcinoma. RESULTS: Of 48 patients evaluable for response, 10 achieved partial responses, for an overall response rate of 21% (95% CI 9.5%-32.5%), and a palliative effect was observed in 52%. The median survival was 9.5 months (18 months for locally-advanced and 5 months for metastatic disease) with a 1-year survival of 34.6% and a median progression-free survival of 4.5 months. Chemotherapy was well tolerated with grades 3 or 4 nausea/vomiting in 12%, diarrhea in 6%, anaemia in 17%, neutropenia in 12%, and thrombocytopenia in 10%. Eleven patients (21%) had Grade 2 peripheral neuropathy. CONCLUSION: The combination of leucovorin, 5-FU and CDDP seems to be an effective palliative treatment, with moderate toxic effects, in advanced pancreatic adenocarcinoma.

[Microangiopathic hemolytic anemia associated with uterine sarcoma: report of a case. Review of the literature]. / Anémie hémolytique microangiopathique associée a un sarcome utérin: rapport d'un cas. Revue de la littérature.

Microangiopathic hemolytic anemia (MAHA) is a rare but severe complication of neoplastic disease. The diagnosis of thrombotic microangiopathy is based on a triad of a hemolytic anemia with schistocytes, thrombocytopenia, and renal failure. Carcinoma-associated MAHA and chemotherapeutic-induced MAHA have been described. Because of differences concerning prognosis and treatment it is important for the clinician to distinguish these two syndromes. However, to our knowledge, this is the first case of a sarcoma-associated thrombotic microangiopathy.

High dose chemotherapy with ifosfamide, carboplatin, and etoposide combined with autologous bone marrow transplantation for the treatment of poor-prognosis germ cell tumors and metastatic trophoblastic disease in adults.

BACKGROUND: A Phase I-II trial to assess the toxicity and efficacy of a tandem high dose chemotherapy combining ifosfamide, carboplatin, and etoposide in germ cell tumors and metastatic trophoblastic disease was performed. METHODS: Thirty-nine patients, with a total of 22 testicular tumors, 9 extragonadal germ cell tumors, 3 ovarian germ cell tumors, and 5 cases of metastatic trophoblastic disease, received tandem high dose therapy combining ifosfamide (7500-12,500 mg/m2), carboplatin (875-1225 mg/m2), and etoposide (1000-1250 mg/m2), followed by bone marrow reinfusion. Among the 39 patients, 33 were refractory to cisplatin- or carboplatin-based regimen and the response of 37 could be evaluated; 69 cycles of this tandem high dose therapy were administered. RESULTS: The overall response rate was 46%, including a complete response (CR) rate of 35%. Of 21 patients with testicular tumors who could be evaluated, 10 (47%) achieved a CR. No CRs were obtained in patients with refractory extragonadal germ cell tumors. Nine partial responders after the first cycle became complete responders after the second. Nine (23%) of the patients were long term survivors (> 18 months), 7 of them in continuous CR. Side effects primarily were renal toxicity and enterocolitis. Seven patients (18%) died of therapy-related be explored and the maximum tolerated doses of this three-drug regimen remain to be determined. CONCLUSION: This tandem therapeutic regimen is able to overcome resistance to a platinum-based regimen in highly refractory germ cell tumors and gestational trophoblastic disease and to cure a number of patients.

[Therapeutic intensification and hematopoietic stem cell autotransplantation in the treatment of solid tumors in adults: principles, realization and application to the treatment of germ cell, trophoblastic, breast, ovarian and small-cell bronchial tumors. 1]. / Intensification thérapeutique et autotransplantation de cellules-souches hématopoïétiques dans le traitement des tumeurs solides de l'adulte: principes, réalisation et application au traitement des tumeurs germinales, trophoblastiques, mammaires, ovariennes et bronchiques à petites cellules. Première partie.

Autologous bone marrow transplantation for the treatment of solid tumors in adults remains an uncommon therapeutic approach. The feasibility of such high-dose therapies is clearly proved, especially with the advent of hematopoietic growth factors and the rescue by the peripheral stem cells to reduce the duration of the chemotherapy-induced myeloid aplasia. The question is to exactly define the place of high-dose therapy in the land of solid tumors. For the treatment of primary chemoresistant gonadal germ-cell tumors, the possibility to cure the patients and the interest of high-dose therapy with autologous bone marrow transplantation are clearly demonstrated. As consolidation for the treatment of poor prognosis tumors, the place of high-dose therapies remains moot. For the treatment of chemoresistant extragonadal germ-cell tumors, especially for primary mediastinal tumors, the level of resistance to cisplatin-based chemotherapy regimens is generally too high to be overcome by intensive therapies given as single course or as tandem courses. However in association with debulking surgery, this therapeutic approach has to be considered for some patients. In the treatment of poor prognosis breast cancer, high-dose therapy with autologous bone marrow transplantation or with peripheral stem cells support is able to convert some patients with partial response into complete responders. However, the consequences on overall survival and on disease-free survival are not evident. For metastatic breast cancer and for poor-prognosis tumors (inflammatory breast cancer, axillary metastatic nodes > or = 8), the interest of high-dose therapy has to be determined by randomized studies. These studies are ongoing in USA and in Europe. For the treatment of poor-prognosis ovarian cancer, the situation is more difficult to appraise. Once again, randomized studies have to be done to precisely define the place of high-dose therapy. In the land of small-cell lung carcinomas, high-dose therapy is actually forsaken by most of authors, even for limited diseases. The results of previous studies are disappointing. Moreover, occult medullary micrometastases involvement is frequent, once again even in limited diseases. However new therapeutic associations, as the ICE regimen (IFM, Carboplatin, VP-16) delivered as single or tandem therapy, have to be studied, especially as early consolidation therapy for the treatment of limited small-cell lung carcinomas.

Treatment of unresectable hepatocellular carcinoma with a combination of human recombinant alpha-2b interferon and doxorubicin: results of a pilot study.

Based on the in vitro and in vivo potentiation of the cytotoxic activity of chemotherapeutic agents by the interferons, a pilot study combining human recombinant alpha-2b interferon (IFN) and doxorubicin was conducted for the treatment of unresectable, histologically proven hepatocellular carcinoma. Between March 1988 and May 1990, 21 patients (median age: 60 years, range: 29-76) entered the study. The dose of doxorubicin was fixed at 35 mg/m2, every 3 weeks. The dose of alpha-2b IFN was 6 million U/m2 per day, 5 days a week. 3 patients (14%) obtained a partial response lasting 11, 16 and 30 months, and 1 had a stable disease during 8 months. The other 17 patients died within a median survival time of 4 months. All patients experienced flu-like symptoms. 7 patients experienced WHO grade III-IV haematological toxicity. We conclude that the association of alpha-2b IFN and doxorubicin is feasible, with respect to the use of doxorubicin at an inferior dose level than the same agent used without IFN. The response rate is comparable to that observed with doxorubicin used alone. Further phase I studies and randomised trials are required to confirm the role of this regimen in the treatment of unresectable hepatocellular carcinoma.

[Salvage chemotherapy of non-seminomatous germ cell tumors. Phase II trial of a combination of etoposide, ifosfamide and high-dose cisplatin]. / Chimiothérapie de deuxième intention des tumeurs germinales non séminomateuses. Essai phase II d'une association d'étoposide, ifosfamide et cisplatine haute dose (VIhP).

Between october 1985 and january 1988, 32 patients with heavily pretreated refractory or relapsing non seminomatous germ cell tumors were included in a phase II trial using etoposide, ifosfamide and high dose cisplatin (VIhP). Eight of 30 evaluable patients (29 per cent) achieved complete response with VIhP treatment alone or followed by surgical excision of residual lesions. Five patients in complete remission relapsed at 3, 4, 5.5 and 7 months, and 3 patients remained continuously free of disease at 17, 21 and 22 months. Severe myelosuppression with a WBC nadir less than 500/mm3 and a platelet nadir less than 20,000/mm3 was observed in 73 per cent of the patients, and renal toxicity (WHO grade 2 or 3) in 29 per cent. The VIhP regimen for salvage therapy gives the same rate of long term survivors than the regimen with conventional cisplatin dosage (VIP) but is much more toxic and cannot be recommended.
