Neutrophil-to-lymphocyte ratio and chemotherapy response score as prognostic markers in ovarian cancer patients treated with neoadjuvant chemotherapy.

BACKGROUND: Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) is the recommended approach in patients with advanced epithelial ovarian cancer (EOC). However, most patients eventually relapse despite the initial high response rate to chemotherapy. Neutrophil-to-lymphocyte ratio is a well-known biomarker that reflects severe inflammation, critical illness, and mortality in various diseases. Chemotherapy response score (CRS) and neutrophil-to-lymphocyte ratio (NLR) have been identified as potential biomarkers of platinum resistance and disease prognosis. We retrospectively evaluated 132 patients with stage IIIc or IV ovarian/fallopian tube/primary peritoneal cancer who had received NACT followed by IDS from 01/01/2003 to 31/12/2018. CRS was assessed on omental specimens collected from IDS according to ICCR guidelines. RESULTS: Median age was 64.57 years (SD: 9.72; range 39.2-87.1). Most ovarian tumors were serous epithelial (90.9%; 120/132). An elevated NLR (defined as > 3) was observed in 72% (95/132) of patients in contrast with 28% (37/132) of patients characterized by low NLR status. Median PFS (mPFS) and median overall survival (mOS) were 13.05 months (95% CI: 11.42-14.67)) and 34.69 months (95% CI: 23.26-46.12) respectively. In univariate analysis, CRS3 score was significantly associated with prolonged mPFS (CRS1/2: 12.79 months vs CRS3: 17.7 months; P = 0.008). CRS score was not associated with mOS (P = 0.876). High NLR was not significantly associated with mPFS (P = 0.128), however it was significantly associated with poor mOS (P = 0.012). In multivariate analysis, only performance of surgery maintained its statistical significance with both PFS (P = 0.001) and OS (P = 0.008). CONCLUSION: NLR could serve as a useful predictor of OS but not PFS in ovarian cancer patients receiving NACT. In accordance with our previous study, CRS score at omentum was found to be associated with PFS but not OS in ovarian cancer patients treated with NACT and IDS.

Biomarkers that would predict response to neoadjuvant chemotherapy in advanced ovarian cancer patients are eagerly needed:• Neutrophil to Lymphocyte Ratio (NLR) is an indicator of systemic inflammatory response to the malignancy.• NLR was evaluated in 132 patients undergoing Neoadjuvant Chemotherapy for advanced ovarian cancer.• Elevated NLR was associated with worse prognosis.• No association between NLR and response to chemotherapy was noted.

Axitinib as a third or further line of treatment in renal cancer: a single institution experience.

BACKGROUND: Kidney cancer is a lethal neoplasm that affects several thousands of people every year. Renal cell carcinoma (RCC) is the most common histologic type. Recent developments in the therapeutic approach include antiangiogenic targeted approaches and Immunotherapy. Thus, the therapeutic algorithm of RCC patients and the survival outcomes have changed dramatically. METHODS: Herein we present a retrospective study of the patients treated in our Department with an antiangiogenic agent -Axitinib, a tyrosine kinase inhibitor- as a third or further line treatment. Statistical analysis was performed with SPSS, including the available clinicopathological data of the patients included. RESULTS: Axitinib was found to be active in patients who received this treatment beyond second line. The toxicity profile of this regimen did not reveal any unknown adverse events. CONCLUSIONS: Our real world data reflect that axitinib is a safe and effective option, even beyond the second line.

Metastatic soft tissue sarcoma: current treatment landscape and future perspectives.

INTRODUCTION: The therapeutic armamentarium for advanced soft tissue sarcoma (STS) has increased over the last few years. Doxorubicin monotherapy or in combination is now the established first line treatment. Beyond first line treatment, no standard therapy has been established. Novel drugs have reached the late-clinical stage development demonstrating to be effective in controlled studies. While these novel treatments can be beneficial to a subset of patients, even producing long lasting remissions, a significant fraction of the STS population derives limited benefit. This is due to the fact that STS is a very heterogeneous disease with different histopathologic features, biological characteristics and clinical behaviour. Areas covered: The primary aim of this review is to summarize data from recent phase III clinical trials in unselected STS population, and to discuss their impact on the current clinical practice. Phase I-II trials of special interest are discussed as well. Expert commentary: Although our efforts in this research task are ongoing, the integration of biological therapies, the anti-angiogenesis targeted treatments as well as immunotherapy that may further improve the long term control of advanced STS are of special clinical interest. Clinical management of advanced STS should be tailored to each patient in order to optimize therapy.

Expression of E-cadherin in primary endometrial carcinomas: clinicopathological and immunohistochemical analysis of 30 cases.

INTRODUCTION: Decreased expression of E-cadherin has been associated with poorly differentiated endometrial carcinomas and poorer outcomes. AIM: The purpose of this study was to examine the distribution of E-cadherin immunohistochemical expression in specimens from primary endometrial carcinomas and its relation to classical clinicopathological prognostic factors. MATERIALS AND METHODS: Surgically-resected tissues of 30 patients with primary endometrial carcinomas were studied. Histological type and grade, depth of myometrial invasion, lymph-vascular space invasion, fallopian tube or ovarian invasion, and the presence of tumoral necrosis were evaluated. Immunohistochemical examination was performed on deparaffinized four-microm-thick sections. RESULTS: The mean age of patients was 65 years (+/- 11.41). The 63.54% of carcinomas were moderately/poorly differentiated. No statistical correlation was found between the score or intensity of E-cadherin immunohistochemical staining (strong or moderate positive expression) and the clinicopathological factors tested. CONCLUSIONS: The association of E-cadherin immunoreactivity with the standard clinicopathological factors seemed to be contradictory. The classical clinicopathological factors remain the most important prognostic parameters.

Gastric calcifying fibrous tumor: a very rare case report.

Calcifying fibrous tumor is a very rare benign mesenchymal tumor which shows a predilection for soft tissue, mesentery and peritoneum. Up to date only 7 cases have been reported in the literature confined to the gastric wall. We report a rare case of a calcifying fibrous tumor of the stomach in a 60-year-old man who presented with dyspepsia, flatulence and feeling weight. A clinical and laboratory investigation was performed with normal results. Gastroscopy revealed a bulge in the gastric body measuring 1 cm with normal overlying mucosa, and mucosal biopsies showed chronic gastritis. Endoscopic ultrasound of the gastric bulge showed a 1 × 0.8 cm hypoechoic lesion involving the gastric wall. After the above finding a wedge resection of the stomach was performed. Microscopically the lesion consisted of well-circumscribed hypocellular hyalinized fibrosclerotic tissue with lympoplasmatic infiltrates, lymphoid aggregates and psammomatous calcifications. Lesional cells were positive for vimentin and factor XIII and negative for actin, desmin, S100p, CD117, CD34, CD31 and ALK-1. The lesion involved the muscularis propria with variable submucosal extension. Calcifying fibrous tumor has shown an excellent prognosis with recurrences being rare and showing the same morphology as the primary lesion.

Synchronous primary adenocarcinoma and ancient schwannoma in the colon: an unusual case report.

Gastrointestinal schwannomas are uncommon stromal tumors of the intestinal tract and colon schwannomas are extremely rare. We report a rare case of ascending colon schwannoma with associated synchronous adenocarcinoma of the sigmoid colon. A 68-year-old man presented with a 20-day history of bleeding per rectum. Colonoscopy revealed a mass of 4.2 cm in diameter with endoluminal protrusion in the sigmoid colon and a second submucosal tumor in the ascending colon. Surgical intervention was suggested and ileo-hemicolectomy was done. Microscopically, the submucosal tumor of 4 cm in diameter showed features of schwannoma with degenerative change (ancient schwannoma). Lesional cells were positive for S100p and negative for actin, desmin, CD34, CD117, and pankeratin. The mass showed features of an invasive moderately differentiated adenocarcinoma. Colon schwannoma is a rare submucosal tumor, and the incidental occurrence with adenocarcinoma has not been well described in the literature.

Borderline clear cell adenofibroma of the ovary associated with ovarian endometriosis: a case report.

Clear cell tumours of the ovary are relatively uncommon. Most of them are clear cell carcinomas. Benign and borderline clear cell tumours are extremely rare and almost always fibromatous. We report a case of a 34-year-old woman. Ultrasound and computed tomography showed a right ovarian mass 8 cm in diameter. The patient underwent right salpingo-oophorectomy. Microscopic examination revealed glands and cysts different in size and shape within an abundant stromal component without evidence of stromal invasion. Many cysts and glands were lined by a single layer of flattened, cuboidal or hobnail cells with mild to moderate cytologic atypia and prominent nucleoli. Psammomatous calcifications were occasionally indentified. Features of endometriosis were also present adjacent to the tumour. Lesional cells were positive for Ker 7 and CA125. Staining for p53 was focally positive. Based on the above characteristic morphologic and immunohistochemical findings a diagnosis of borderline clear cell adenofibroma was made. The patient was free of recurrence four years after surgery.

Primary cutaneous apocrine carcinoma of sweat glands: a rare case report.

Cutaneous apocrine gland carcinoma, a subtype of sweat gland carcinoma, is a very rare malignancy, and only few cases have been reported in the literature. Many of these carcinomas are indolent and slowly developing, but some are rapidly progressive. The treatment of choice is wide local excision with clear margins, with or without lymph node dissection. We report a case of a 67-year-old man who came to our hospital with an ulcerated nodule in the right axilla measuring 1 × 0.8 cm. Histological evaluation showed features of an apocrine gland carcinoma arising in an area of high apocrine gland density.

Primary malignant mixed müillerian tumour of the fallopian tube. Report of a case.

Malignant mixed müllerian tumour of the fallopian tube is an extremely rare lesion and to date only approximately 50 cases have been reported. The tumour is seldom distinguished preoperatively from other more common lesions or ovarian cancer. We report a case of a 60-year-old woman who presented to our hospital with pelvic pain. There was no clinical evidence of ascites or adenopathy. Ultrasound and abdominal and pelvic computed tomography showed a left adnexal mass. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were carried out. Grossly the left side of the fallopian tube was dilated and the cut surface revealed a solid mass filling the entire lumen. Histological examinations showed a malignant mixed müllerian tumour. The tumor was an admixture of both carcinomatous and sarcomatous elements. The carcinomatous element was composed of well to moderately differentiated squamous cell carcinoma and the sarcomatous component was made up of anaplastic spindle shaped cells with hyperchromatic nuclei. An immunohistochemical study was performed. The patient was admitted to the anticancer hospital for further treatment. The prognosis of a primary malignancy of the fallopian tube is poor and depends more on staging than on histologic type and grade.

Synchronous endometrioid carcinoma of the uterine corpus and ovary. A case report and review of the literature.

Synchronous endometrioid carcinoma of the uterine corpus and ovary is an uncommon but well recognized event. Diagnosis as either a separate independent primary or as a metastatic tumor requires careful consideration of a number of gross and histological features. These features illustrate the criteria helpful in distinguishing independent primaries from metastatic carcinomas which have a different therapeutic implication. The possible link between fertility drugs and carcinogenesis still remains controversial. We report a case of a 52-year-old woman who came to our hospital with a cystic left ovarian mass (8 cm). Hysterectomy and bilateral salpingo-oophorecromy were carried out. Histological examinations showed well differentiated endometrioid ovarian cancer and well differentiated endometrioid endometrial cancer. The endometrial tumor was intramucosal without myometrial or vascular invasion and was associated with atypical complex hyperplasia. The woman had not been previously treated with ovulation induction drugs. She was free of recurrence two years after surgery. Patients with synchronous endometrioid tumors of the endometrium and ovary are generally younger than reported for either endometrial adenocarcinomas or ovarian adenocarcinomas. They tend to be low grade and early stage and are frequently associated with endometriosis. The prognosis of endometrioid type carcinomas is better than other histological types of carcinoma.
