- BACKGROUND: Hepatocellular cancer (HCC), as well as cholangiocellular cancer (CCC), has an extremely poor prognosis due to the extent of tumor at diagnosis and the underlying liver disease. Sirolimus is used in the transplantation setting as an immunosuppressive agent, but it also possesses antiproliferative and antiangiogenic properties. The objective of the study was to evaluate the effect of sirolimus on HCC and CCC. METHODS: In a prospective single-arm protocol, the tumor response to sirolimus as the primary endpoint was studied in 21 patients with advanced HCC and nine with CCC. Sirolimus was administered once daily by mouth, with the dose adjusted to a serum trough level between 4 and 15 mug/ml. Tumor response was evaluated by computed tomography (CT) or magnetic resonance imaging (MRI), according to the Response Evaluation Criteria in Solid Tumors (RECIST), every third month. Secondary measures were overall survival, time to tumor progression, tumor markers, and side effects. RESULTS: Of the patients with HCC, one had partial remission (PR) and fi ve patients had stable disease (SD) at 3 months. Of the patients with CCC, three had SD. The median survival for patients with HCC was 6.5 months (range, 0.2-36 months) and that for patients with CCC was 7 months (range, 2.6-35 months). CONCLUSION: Treatment of HCC and CCC with sirolimus can induce temporary PD or SD. This pilot study indicates that sirolimus might be a promising drug for this treatment, but further clinical studies elucidating the biological effects are advocated.

- BACKGROUND: Chemotherapy efficacy is largely dependent on treatment adherence, defined by the relative dose intensity (RDI). Identification of new modifiable risk factors associated with low RDI might improve chemotherapy delivery. Here, we evaluated the association between low RDI and pre-chemotherapy factors, including patient- and treatment-related characteristics and markers of inflammation.METHODS: This exploratory analysis assessed data from 267 patients with early-stage breast cancer scheduled to undergo (neo-)adjuvant chemotherapy included in the Physical training and Cancer (Phys-Can) trial. The association between low RDI, defined as < 85%, patient-related (age, body mass index, co-morbid condition, body surface area) and treatment-related factors (cancer stage, receptor status, chemotherapy duration, chemotherapy dose, granulocyte colony-stimulating factor) was investigated. Analyses further included the association between RDI and pre-chemotherapy levels of interleukin (IL)-6, IL-8, IL-10, C-reactive protein (CRP) and Tumor Necrosis Factor-alpha (TNF-α) in 172 patients with available blood samples.RESULTS: An RDI of < 85% occurred in 31 patients (12%). Univariable analysis revealed a significant association with a chemotherapy duration above 20 weeks (p < 0.001), chemotherapy dose (p = 0.006), pre-chemotherapy IL-8 (OR 1.61; 95% CI (1.01; 2.58); p = 0.040) and TNF-α (OR 2.2 (1.17; 4.53); p = 0.019). In multivariable analyses, inflammatory cytokines were significant association with low RDI for IL-8 (OR: 1.65 [0.99; 2.69]; p = 0.044) and TNF-α (OR 2.95 [1.41; 7.19]; p = 0.007).CONCLUSIONS: This exploratory analysis highlights the association of pre-chemotherapy IL-8 and TNF-α with low RDI of chemotherapy for breast cancer. IL-8 and TNF-α may therefore potentially help to identify patients at risk for experiencing dose reductions. Clinical trial number NCT02473003 (registration: June 16, 2015).

- PURPOSE: To evaluate the prolonged release (PR) of the long-acting somatostatin analog lanreotide in patients with gastrointestinal neuroendocrine tumors and its effect on hormone-related symptomatology, tumor markers, tumor size, tolerability, and quality of life (QOL). PATIENTS AND METHODS: Eligible patients had the following substantial daily symptoms: for patients with carcinoid tumors, three or more stools and/or 1.5 or more flushing episodes; for patients with gastrinoma, greater than 50% elevated basic acid output; and for patients with vasoactive intestinal peptide-secreting tumors (VIPomas), four or more stools and/or a stool volume of >/= 800 mL, a measurable tumor, and an elevated biochemical tumor marker (>/= two times the upper limit of the normal reference range). Lanreotide PR was administered intramuscularly every 14 days at 30 mg for 6 months. We measured efficacy by studying symptoms, tumor markers, tumor size, and QOL. Side effects were scored according to the National Cancer Institute's toxicity grading system and ultrasound examination of the gallbladder. RESULTS: Fifty-five patients were included in the study (48 patients with carcinoid tumors, six patients with gastrinoma, and one patient with VIPoma). Symptomatic improvement (> 50% reduction) occurred in 38% of the assessable patients with carcinoid tumors, in 67% of the gastrinoma patients, and in the VIPoma patient. Tumor markers normalized in two of 45 assessable patients, 19 patients exhibited a reduction (> 50%), 19 patients exhibited no change, and tumor markers rose by more than 50% in five patients. Tumor size was reduced in two of 31 assessable patients and remained stable in 25 patients; four patients experienced progression. QOL assessments after 1 month showed improvements in emotional and cognitive function, and diminished fatigue, sleeping disorders, and diarrhea. Eight of 30 assessable patients developed gallstones. CONCLUSION: Lanreotide PR is a well-tolerated somatostatin analog with significant clinical, biochemical, and antitumor effects that bring about a significant improvement in QOL for patients with neuroendocrine tumors.

- Background: The aim of the present study was to investigate the incidence and hallmarks of long-term survivors of recurrent ovarian carcinoma (LTSROC) in a large-scale retrospective cohort of patients from a multicenter study group. Methods: We performed a regional multicenter retrospective study between January 1986 and September 2021 using clinical data collected under the central pathological review system. Patients who underwent surgery for primary OC at diagnosis and developed recurrent tumors after the initial treatment were included. We defined LTSROC as patients who survived for 5 years or longer after initial tumor recurrence and examined factors affecting the long-term survival of ROC and outcomes of LTSROC. Results: We collected information on patients with malignant ovarian tumors and finally 657 of them that developed ROC were included in the study population. Sixty-eight (10.4%) patients were LTSROC while 399 (60.7%) were short-term survivors of recurrent ovarian carcinoma. In a multivariate logistic regression analysis, negative ascites cytology [odds ratio (OR) 1.865; 95% CI 1.026–3.393; p = 0.041] and a recurrence-free interval (RFI) of 1 year or longer (OR 2.896; 95% CI 1.546–5.425; p < 0.001) were identified as independent factors associated with LTSROC. Approximately 80% of LTSROC presented with solitary recurrent tumors. Furthermore, more than 50% of LTSROC underwent tumor debulking surgery for the first recurrent tumor with or without chemotherapy. Conclusion: RFI of 1 year or longer and negative ascites cytology in the initial surgery were identified as independent predictive factors for LTSROC.
