Anal cancer in Sweden 2015-2019. Implementation of guidelines, structural changes, national registry and early results.

BACKGROUND: Squamous cell cancer of the anus is an uncommon malignancy, usually caused by human papilloma virus (HPV). Chemoradiotherapy (CRT) is the recommended treatment in localized disease with cure rates of 60-80%. Local failures should be considered for salvage surgery. With the purpose of improving and equalizing the anal cancer care in Sweden, a number of actions were taken between 2015 and 2017. The aim of this study was to describe the implementation of guidelines and organizational changes and to present early results from the first 5 years of the Swedish anal cancer registry (SACR). METHODS: The following were implemented: (1) the first national care program with treatment guidelines, (2) standardized care process, (3) centralization of CRT to four centers and salvage surgery to two centers, (4) weekly national multidisciplinary team meetings where all new cases are discussed, (5) the Swedish anal cancer registry (SACR) was started in 2015. RESULTS: The SACR included 912 patients with a diagnosis of anal cancer from 2015 to 2019, reaching a national coverage of 95%. We could show that guidelines issued in 2017 regarding staging procedures and radiotherapy dose modifications were rapidly implemented. At baseline 52% of patients had lymph node metastases and 9% had distant metastases. Out of all patients in the SACR 89% were treated with curative intent, most of them with CRT, after which 92% achieved a local complete remission and the estimated overall 3-year survival was 85%. CONCLUSIONS: This is the first report from the SACR, demonstrating rapid nation-wide implementation of guidelines and apparently good treatment outcome in patients with anal cancer in Sweden. The SACR will hopefully be a valuable source for future research.

Equal cancer treatment regardless of education level and family support? A qualitative study of oncologists' decision-making.

OBJECTIVE: Treatment gradients by socioeconomic status have been observed within cancer care in several countries. The objective of this study was to explore whether patients' educational level and social network influence oncologists' clinical decision-making. DESIGN: Semi-structured interviews on factors considered when deciding on treatment for cancer patients. Interviews were transcribed and analysed using inductive qualitative content analysis. SETTING: Oncologists in Swedish university- and non-university hospitals were interviewed in their respective places of work. PARTICIPANTS: Twenty Swedish clinical oncologists selected through maximum-variation sampling. PRIMARY AND SECONDARY OUTCOME MEASURES: Elements which influence oncologists' decision-making process were explored with focus on educational level and patients' social support systems. RESULTS: Oncologists consciously used less combination chemotherapy for patients living alone, fearing treatment toxicity. Highly educated patients were considered as well-read, demanding and sometimes difficult to reason with. Patients with higher education, those very keen to have treatment and persuasive relatives were considered as challenges for the oncologist. Having large groups of relatives in a room made doctors feel outnumbered. A desire to please patients and relatives was posed as the main reason for giving in to patients' demands, even when this resulted in treatment with limited efficacy. CONCLUSIONS: Oncologists tailor treatment for patients living alone to avoid harmful side-effects. Many find patients' demands difficult to handle and this may result in strong socioeconomic groups being over-treated.

Metastatic colorectal cancer: current treatment and future options for improved survival. Medical approach--present status.

BACKGROUND: Metastatic colorectal cancer has a poor prognosis, and the majority of patients are left with palliative measures. The development seen using medical treatments are reviewed. MATERIAL AND METHODS: A systematic approach to the literature-based evidence of effects from palliative chemotherapy and targeted drugs was aimed at. RESULTS: The continuous improvements during the past 20-25 years have been documented in several large conclusive trials. At the end of the 1980s, the evidence that chemotherapy should be used at all was very limited, whereas presently most patients can be offered three lines of chemotherapy with or without a targeted drug based upon good scientific evidence. Median survival in trials has gradually improved from about 6 months to above 24 months in the most recent trials. Survival in the populations has, however, not improved to the same extent. Several important issues remain to be solved, such as the best sequence of treatments, what regimens to use in various situations, when to start and when to stop if a response is seen, whether cure may be possible in a small subset of patients, and socioeconomic issues. Integration of surgery and other local methods have further improved outcome for some individuals, but must be fine-tuned. CONCLUSIONS: Progress has been rapid in advanced colorectal cancer. This is likely a result of well-designed trials in collaboration between academy and industry, showing a great interest in the disease. A multi-professional approach and future collaborations may hopefully introduce new treatment concepts, further improving outcome.
