Brief Summary

The main idea behind MICRO-LEARNER is to provide new insights about the response of healthy tissues to radiation by using information from the micro-environment obtained by biological measurements and imaging. This new knowledge will be included in current available predictive models of radio-induced toxicity, thus allowing to add unique biological characteristics of patients to dosimetry and treatment/clinical related variables. MICRO-LEARNER focuses on prostate cancer (PCa) and head-and-neck cancer (HNCa). For both cancers, radiotherapy is effectively used as curative treatment, in single modality or within a multidisciplinary approach including surgery (PCa) and/or chemotherapy (HNCa). Prediction and reduction of radio-induced side effects are becoming a priority: for PCa, high survival rates should be accompanied by a very low rate of moderate/severe toxicities; for HNCa, there is the need to tailor radiation dose according to disease recurrence risk profile. The shared aim of both cancers is to balance the improvement in outcome with a well-tolerated toxicity profile. Recent research indicates that the intestinal/salivary bacteria are strongly suspected of being very important in mediating the response to inflammation and lesions. Although their balance deeply changes during radiotherapy, studies done so far in the field of the microbiota-host relationship in radiotherapy have not addressed their role in insurgence of radiation toxicity. In this study, the investigators will assess how microbial populations evolve and how this influences the host and radiation induced toxicity in a significant number of patients. Moreover, the individual response at the tissue microstructure level, through analysis of images with advanced bioengineering techniques, will be determined. Results from this research, besides suggesting new ways to predict patients at risk of relevant side-effects, may also suggest possible treatments to change the baseline microbiota of patients at high risk or to modify it during therapy, in order to mitigate toxicity. Understanding the microbiota-radiotherapy interaction may thus lead to novel, effective and inexpensive ways of assessing and managing complications of cancer treatment.

Outcome Measures

Primary Outcomes (1)

  • Acute toxicity

    If any, acute (\<within 90 days from radiotherapy completion) Grade 1, Grade 2, Grade 3-4 disorder, according to the Common Terminology Criteria for Adverse Events (CTCAE) grading system, and its association with clinical variables, absorbed dose, microbioma characteristics and radiomic features.

    <90 days after radiotherapy

Secondary Outcomes (1)

  • Late toxicity

    3 months - 3 years after radiotherapy

Interventions

Patients will receive radiotherapy for prostate cancer and possible adjuvant hormone therapies as foreseen by international guidelines. No modification of standard regimens is considered. PCa patients are treated with 78 Gy, 2Gy/fraction, in exclusive setting and with 70 Gy, 2Gr/fraction in the post-prostatectomy setting. Lymph node irradiation is performed (50 Gy, 2Gy/fraction) when indicated by risk class.

PCa patients - Discovery cohortPCa patients - Validation cohort

Patients will receive radiotherapy for head and neck cancer and possible concomitant chemotherapies as foreseen by international guidelines. No modification of standard regimens is considered. In curative setting, HNCa patients are treated at a total dose of 70 Gy, 59.4 Gy and 56.1 Gy in 33 fractions to high risk Planning Target Volume (PTV), intermediate risk and low risk PTV, respectively. In high risk post-operative setting they are treated with 66 Gy (according to histopathological features), 60 Gy and 56.1 Gy to high, intermediate and low risk PTV, respectively; while, in intermediate risk post-operative case, intermediate and low risk PTV are irradiated with 60 Gy and 54 Gy, respectively. Chemotherapy will be platinum based (weekly or 3-weekly cisplatin).
