RESUMO
BACKGROUND: The impact of the first coronavirus disease 2019 (COVID-19) wave on cancer patient management was measured within the nationwide network of the Unicancer comprehensive cancer centers in France. PATIENTS AND METHODS: The number of patients diagnosed and treated within 17 of the 18 Unicancer centers was collected in 2020 and compared with that during the same periods between 2016 and 2019. Unicancer centers treat close to 20% of cancer patients in France yearly. The reduction in the number of patients attending the Unicancer centers was analyzed per regions and cancer types. The impact of delayed care on cancer-related deaths was calculated based on different hypotheses. RESULTS: A 6.8% decrease in patients managed within Unicancer in the first 7 months of 2020 versus 2019 was observed. This reduction reached 21% during April and May, and was not compensated in June and July, nor later until November 2020. This reduction was observed only for newly diagnosed patients, while the clinical activity for previously diagnosed patients increased by 4% similar to previous years. The reduction was more pronounced in women, in breast and prostate cancers, and for patients without metastasis. Using an estimated hazard ratio of 1.06 per month of delay in diagnosis and treatment of new patients, we calculated that the delays observed in the 5-month period from March to July 2020 may result in an excess mortality due to cancer of 1000-6000 patients in coming years. CONCLUSIONS: In this study, the delays in cancer patient management were observed only for newly diagnosed patients, more frequently in women, for breast cancer, prostate cancer, and nonmetastatic cancers. These delays may result is an excess risk of cancer-related deaths in the coming years.

We have compared different modes of rehabilitation after breast cancer surgery on a population of 257 patients treated at the Institute Gustave-Roussy in 1990 and 1991. The mode of rehabilitation was randomized according to a 2 X 2 design, between physiotherapy alone, shoulder movement alone, both or neither. Treatment began the day after breast surgery and continued for 7 days. Afterwards, all patients had physiotherapy and shoulder movements until the end of hospitalisation. Treatment efficacy was evaluated at day 7 by the volume of lymph drained, and by degree of shoulder movement. The volume of lymph collected by day 7 was reduced in the physiotherapy groups, but was not modified in the groups with shoulder movement. The degree of motion was larger in the group who had had both physiotherapy and shoulder movement. The frequencies of complications at day 7 and later were similar in the four treatment groups, but locoregional pain was less frequent in the two groups with shoulder movement than in the two other groups. An early treatment including both physiotherapy and shoulder movement seems advisable.

Recently developed drugs are ten to one hundred fold more costly than the chemotherapies of the past while the number of eligible patients and the average duration of treatments are ever increasing. The combined effect of these trends makes budgeting a daunting task, in particular for hospitals with budgetary allocation. Balancing budgets became difficult with the arrival of taxanes, but innovative therapies based on biotechnological advances will further increase the financial slide. Hospital running costs can not be infinitely reduced. Therefore, new rules that govern the financing of innovative therapies become mandatory and budgetary allocations based on DRG evaluations will no longer be feasible.

In 2013, about 6000 patients were treated with brachytherapy, the number diminishing by 2.6% per year since 2008. Prostate, breast and gynecological cancers are the most common types of cancers. Since 2008, the number of brachytherapy facilities has decreased by 18%. In medicoeconomic terms, brachytherapy faces many problems: the coding system is outdated; brachytherapy treatments cost as much as internal radiation; fees do not cover costs; since iridium wire has disappeared from the market, the technique will be transferred to more expensive high-speed or pulse dose rates. The French financing grid based on the national study of costs lags behind changes in such treatments and in the best of cases, hospitals resorting to alternatives such as in-hospital brachytherapy are funded at 46% of their additional costs. Brachytherapy is a reference technique. With intense pressure on hospital pricing, financing brachytherapy facilities will become even more problematic as a consequence of the disappearance of iridium 192 wires. The case of brachytherapy illustrates the limits of the French financing system and raises serious doubts as to its responsiveness.

A mortality study of French Polynesia in the period 1984-92, although limited by the small population living close to the test sites and the high proportion of deaths attributed to ill-defined causes, found no excess of cancer that could confidently be attributed to the 41 atmospheric test explosions in 1966-74. A study of cancer incidence is planned.

BACKGROUND: Between 1966 and 1974, France performed 41 atmospheric nuclear weapon tests in the Mururoa and Fangataufa atolls in French Polynesia. METHODS: We performed a geographic analysis of thyroid cancer incidence, using data from the cancer registry of French Polynesia, medical evacuation files, insurance records and hospital and pathology laboratory files. RESULTS: A total of 153 thyroid cancers were diagnosed between 1985 and 1995 in the population born before 1976 and residing in French Polynesia. The incidence of thyroid cancer was 2-3 times larger in French Polynesia than in Maoris of New Zealand and Hawaiians of Hawaii. Based on few cases, a nonsignificant (p = 0.1) increase with decreasing distance between Mururoa and the birth place was observed in women born between 1950 and 1975 for thyroid cancer. CONCLUSION: Because the difference between Polynesian and reference populations was not larger for Polynesians who were children during the tests than for Polynesians born earlier; as would be expected in the case of radioiodine contamination, the high thyroid cancer rates in French Polynesia could hardly be attributed to radioiodine fallout. Nevertheless, a surveillance of the population born close to Mururoa is necessary to confirm or deny the existence of a higher risk of thyroid cancer in this population.

We present the data of the Cancer Registry of French Polynesia (FP) for the 1990-1995 period, highlighting the difference between the incidences among inhabitants born in FP and in immigrants. A total of 1606 incident cases of cancer were registered during the 6-year period from 1990 to 1995, about 90% of which were histologically confirmed. Among these incident cases, 1361 occurred in native French Polynesians (FPs) and 245 in immigrants. Overall cancer incidence was found to be very slightly higher among women in the native population (209/10(5)) than among immigrants (191/10(5)), and lower among men in the native population (186/10(5)) than in the immigrants (241/10(5)). Cervix, corpus uteri, and thyroid cancer incidence rates were higher among women born in FP than among immigrant women. In contrast, colorectal cancer and melanoma incidences rates were lower, and colorectal cancer was similar. Laryngeal cancer incidence was higher among men born in FP than among immigrant men. In contrast, cancers of the oral cavity, colon and rectum, prostate gland, bladder and melanoma were less frequent. This first report, based on the data from the Cancer Registry of French Polynesia, shows high cancer incidence rates in females and low incidence in males born in FP, as compared to those recorded in France; and low cancer incidence rates, as compared to New Zealand Maoris and Hawaiians. For certain cancers, for example colorectal cancer, the incidence in the immigrant population seems to be between that of the native FP population and that of the population living in France, and lower than in New Zealand Maoris and Hawaiians.

Ectopic pregnancies are more frequent among pregnancies resulting from assisted reproductive technology (ART) than in natural conceptions (6% to 7% vs 1%). Fivnat registry has allowed us to analyse 349 ectopics among 6049 clinical pregnancies collected from 1986 to 1990. Ectopic rate decreased with increasing women's age, and since 1986. The risk was also decreased in infertilities of non tubal origin, except for those of unknown origin in which it was at the same level than for tubal infertility. The risk was increased by 65% in stimulation regimens involving clomiphene citrate (CC). The observed decrease from 1986 to 1990 was strongly related to the decrease in use of CC.

OBJECTIVE: To describe the variations in cancer incidence in the population born in French Polynesia (FP) according to the archipelago of birth and to compare this incidence with that of Hawaiians and Maoris. METHODS: Study of data from the Cancer Registry of FP, evacuation files, insurance records, hospital and pathology laboratory files. RESULTS: The overall world standardized cancer incidence in FP during the 1985-95 period in the populations born and living in FP was 246 per 105 person-years (PY) among women and 244 per 105 PY among men. The overall cancer incidence was similar to that in Hawaiians, but 25% lower than in Maoris. Digestive tract cancer incidence was a third that of these two reference populations, whereas that of pharynx, larynx and thyroid cancers was approximately twice as high. The overall cancer incidence rate increased between the period 1985-89 and the period 1990-95 in women, but was stable in men. Colorectal cancer incidence was highest in inhabitants born on the Windward Islands. Women born on the Austral Islands had a higher thyroid and liver cancer incidence and a lower breast cancer incidence. CONCLUSIONS: Further studies are needed to elucidate the variations observed between FP archipelagos, Maoris and Hawaiians.

Osteosarcoma is the most frequent second primary cancer occurring during the first 20 years following treatment for a solid cancer in childhood. Using a cohort study of children treated for a solid cancer, we investigated the incidence and etiology of osteosarcoma as a second malignant neoplasm after childhood cancer in a cohort and a case-control study. We analysed the relationship between the local dose of radiation and the risk of osteosarcoma, taking into account chemotherapy received. A cohort study of 4,400 3-year survivors of a first solid cancer during childhood diagnosed in France or the United Kingdom, between 1942 and 1986, revealed 32 subsequent osteosarcomas. In a nested case-control study, we matched 32 cases and 160 controls for sex, type of first cancer, age at first cancer and the duration of follow-up. Parameters studied were the incidence of osteosarcoma, the cumulative local dose of irradiation and the cumulative dose of chemotherapy received by cases and controls. The risk of a osteosarcoma was found to be a linear function of the local dose of radiation (excess relative risk per gray=1.8), and was found to increase with the number of moles of electrophilic agents per square meter but not with other drugs. No interaction was noted between radiotherapy and chemotherapy. Bilateral retinoblastoma, Ewing's sarcoma and soft tissue sarcoma were found to render patients susceptible to a higher risk of developing an osteosarcoma as a second malignant neoplasm. We recommend long-term surveillance of patients who were treated during childhood for bilateral retinoblastoma, Ewing's sarcoma, soft tissue sarcoma, as well as other first cancer treated with radiotherapy plus high doses of chemotherapy, without focusing exclusively on the radiation field.
