The aim of the research was to discuss a rare case of synchronous malignant peritoneal mesothelioma of the biphasic histological type and neuroendocrine tumor (NET) of the rectum without history of asbestos exposure and to analyze the outcomes of
the performed treatment.
Materials and methods. The 48-year-old patient with synchronous malignant peritoneal mesothelioma of the biphasic histological type and neuroendocrine tumor (NET) of the rectum was analyzed for oncological and clinical outcomes.
Case presentation. During 2 years since manifestation of the disease the patient underwent 3 cytoreductive surgeries (CRS):
removal of the tumor of the sigmoid mesentery, resection of the rectosigmoid junction completeness of cytoreduction (CC) 0 (2017),
omentectomy and partial parietal peritonectomy CC-0 (2017), atypical resection of S2, S4, S5 liver, the removal of the abdominal tumor with left-sided en-block hemicolectomy, partial parietal peritonectomy, argon-plasma coagulation of tumor foci on the mesentery
of the small intestine CC-2 (2018) and Transanal Minimally Invasive Surgery-removal of neuroendocrine rectal tumor (2017). The
patient underwent hyperthermic intraperitoneal chemotherapy (HIPEC) twice (during 2nd and 3rd CRS). Different regimens of HIPEC
were performed: cisplatin + doxorubicin (2017) and metamycin C (2018). The patient received 4 courses of adjuvant chemotherapy
with cisplatin plus pemetrexed in 2017 and 3 courses of the chemotherapy with gemcitabine and carboplatin plus bevacizumab in 2018.
Results. The patient survived 21 months after the detection of malignant peritoneal mesothelioma in 2017 and died 4 months
after the last cytoreductive surgery from the progression of the disease.
Conclusions. Histological subtype of MPMP remains important factor in the prognosis of the disease even on the early
stages though patient had received the most aggressive variant of special treatment. Minimally invasive treatment tactics of NET
demonstrated clinical effectiveness.
