Purpose or Objective

Combined chemoradiotherapy (CRT) with fluorouracil (5FU) and mitomycin (MMC) represents standard of care for patients with locally advanced non-metastatic anal cancer and offers good 5 year survival rates up to 90%. In 02/19 we initiated a observational study assessing the treatment tolerability as well as quality of life before, during and after CRT. We present a planned interim analysis.

Material and Methods

Patients receiving a CRT (VMAT, 1,8/2,2 to 45/55Gy + 2 cycles of 5FU/MMC) as a defintive therapy for anal cancer at the University hospital LMU, Munich were included in this study. Follow up was performed according to the internal hospital standard. Additionally quality of life before, during and after CRT was systematically assessed using the EORTC questionnaires QLQ-C30, QLQ-CR29, the Wexner-, and LARS score.

Results

Between February 2019 und August 2021 20 patients were included (17 female, 3 male) in this prospective study. Patient and tumour characteristics are displayed in Table 1. The median Follow-up was 15 (2-30) months. Distant metastases without local recurrence occured in 2 patients, both of which died. 18 patients are currently free of disease.

Radiotherapy was carried out without interruptions in all patients. Chemotherapy was applied with reduced dose in 6 patients due to acute toxicity. After end of CRT dermatitis I°/II°/III° CTCAE was diagnosed in 4/11/5 patients. Diarrhea I°/II°/III° CTCAE was reported in 5/11/2 patients and fecal incontinence I°/II°/III° CTCAE in 2/3/0 patients.

The overall response rate for the patient questionnaires was 95%/90%/90%/79%/88%/69% at the time of start of CRT/end of CRT/6 weeks/3 months/6 months/12 months after end of CRT.

Median patient reported quality of life were 6 points (range: 1 = very poor to 7 = excellent) before the initiation of therapy, 3 points at the end of CRT and 5/6/6/6 points 6 weeks /3 Months /6 months /12 months after end of therapy.

Conclusion

Our planned interim analysis shows a good compliance to the questionnaire-based assessment of quality of life before, during and after CRT. There was a significant reduction in quality of life under therapy, but also a quick recovery already 6 weeks after end of therapy.
