Purpose To describe a new beam arrangement for preoperative concurrent boost radiotherapy in locally advanced rectal carcinoma. Material and methods Three different volumes, ie posterior pelvis, total mesorectal space, and gross tumor volume plus 2 cm, are selected to receive radiation doses of 47 Gy, 51 Gy, and 54 Gy, respectively, in 24 fractions. There are two prerequisites for the use of such a radiotherapy schedule: complete displacement of the small bowel outside the boost volume, and horizontal positioning of the rectal long axis. Both conditions can be attained by patient positioning on a new device, the “Up-Down Table” (UDT). The dose gradient between the three volumes is realized with two daily arc rotation fields with an isocenter that is different from the three additional multileaf collimator pelvic fields (postero-anterior + 2 laterolateral). Results The treatment data are reported according to the ICRU 62 criteria. A comparison was made between concurrent arc rotation and concomitant static boost techniques. Conclusion The new beam arrangement, with the use of the UDT, allows to administer different radiation doses to three volumes with different tumor cell density in order to obtain the same probability of local response in all target volumes without increasing the toxicity.

Abstract Background Neuroendocrine tumors (NETs) are heterogeneous, widely distributed tumors arising from neuroendocrine cells. Gastrointestinal (GI)-NETs are the most common and NETs of the rectum represent 15, 2% of gastrointestinal malignancies. Poorly differentiated neuroendocrine carcinomas of the GI tract are uncommon. We report a rare case of poorly differentiated locally advanced rectal neuroendocrine carcinoma with nodal and a subcutaneous metastasis, with a cytoplasmic staining positive for Synaptophysin and Thyroid Transcription Factor-1. Case presentation A 72-year-old male presented to hospital, due to lumbar, abdominal, perineal pain, and severe constipation. A whole-body computed tomography scan showed a mass of the right lateral wall of the rectum, determining significant reduction of lumen caliber. It also showed a subcutaneous metastasis of the posterior abdominal wall. Patient underwent a multidisciplinary evaluation, diagnostic and therapeutic plan was shared and defined. The pathological examination of rectal biopsy and subcutaneous nodule revealed features consistent with small-cell poorly differentiated neuroendocrine carcinoma. First line medical treatment with triplet chemotherapy and bevacizumab, according to FIr-B/FOx intensive regimen, administered for the first time in this young elderly patient affected by metastatic rectal NEC was highly active and tolerable, as previously reported in metastatic colo-rectal carcinoma (MCRC). A consistent rapid improvement in clinical conditions were observed during treatment. After 6 cycles of treatment, CT scan and endoscopic evaluation showed clinical complete response of rectal mass and lymph nodes; patient underwent curative surgery confirming the pathologic complete response at PFS 9 months. Discussion and conclusions This case report of a locally advanced rectal NEC with an unusual subcutaneous metastasis deserves further investigation of triplet chemotherapy-based intensive regimens in metastatic GEP NEC.
