Calendula is highly effective for the prevention of acute dermatitis of grade 2 or higher and should be proposed for patients undergoing postoperative irradiation for breast cancer.

Interleukin-2 (IL-2) or/and interferon (IFN) are routinely used for treating patients with metastatic renal cell cancer. However, results have been disappointing, with a majority of treatment failure. Over 6 years, the Groupe Français d'Immunothérapie enrolled 782 patients in successive multicenter trials using cytokine regimens. Univariate and multivariate analyses were performed on this large prospective database to identify prognostic factors for survival. The presence of biological signs of inflammation, short time interval from renal tumor to metastases (<1 year), elevated neutrophil counts, liver metastases, bone metastases, patient performance status (PS), the number of metastatic sites, alkaline phosphatases and hemoglobin levels were predictive of survival outcome. When compared with previous results, our study showed that PS, number of metastatic sites, disease-free interval, biological signs of inflammation and hemoglobin levels can be considered as validated prognostic factors. We also identified four independent factors predictive of rapid progression under cytokine treatment: presence of hepatic metastases, short interval from renal tumor to metastases (<1 year), more than one metastatic site and elevated neutrophil counts. Patients who combined at least three of these factors have >80% probability of rapid progression despite treatment. We think that these results must be taken into account when making the decision to treat with cytokine.

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.
