Aims and background This study aimed to evaluate the significance of characteristics of metastasis as prognostic factors in metastatic renal cell carcinoma (RCC). Patients and methods A total of 148 patients who had received immunotherapy were included in the study. Patients were categorized in various ways according to the characteristics of metastasis, including a synchronous metastasis group (n = 77) vs a metachronous metastasis group (n = 71), and a solitary metastasis group (n = 93) vs a multiple metastases group (n = 55). Results In the synchronous and metachronous metastasis groups, median progression-free survival was 4.3 months (95% confidence interval [CI] 2.9-5.7) and 11.1 months (95% CI 6.7-15.5), respectively (P = 0.004). Median overall survival was 17.1 months (95% CI 9.5-24.7) and 54.8 months (95% CI 38.3-71.3) in the two groups (P = 0.019). In the solitary and multiple metastasis groups, median progression-free survival was 11.0 months (95% CI 6.6-15.5) and 3.9 months (95% CI 2.6-5.2), respectively (P <0.001). Median overall survival was 55.2 months (95% CI 50.7-59.7) and 15.6 months (95% CI 10.9-20.3) in the two groups (P <0.001). Multivariate Cox proportional hazards model analysis using the clinical variables showed that T stage (P = 0.026), number of metastatic sites (P = 0.009) and time to metastasis (P = 0.019) were independent predictors of progression-free survival. Using the same variables, only the number of metastatic sites was an independent prognostic predictor of overall survival (P = 0.014). Conclusions Our findings suggest that the time to metastasis and the number of metastases are important prognostic factors in metastatic RCC.

Aims and background To obtain proof of external validity of the visual analogue scale and re-evaluate the use of this instrument in assessing cancer patients' quality of life. Methods Consecutive patients attending 79 Italian medical oncology and radiotherapy centers over a period of 1 week were asked to fill out both a questionnaire concerning the presence of 19 problems and a 100-mm linear visual analogue scale evaluating their quality of life. Quality of life was rated as “good” and “bad” when given a score of 70-100 and 0-30, respectively. Multifactorial logistic models were used where good and bad quality of life were correlated with explanatory variables including patient and disease characteristics and the presence or absence of the 19 problems. Results Gender, level of education, treatment setting, Karnofsky performance status, disease extent, and the presence of 12 out of 19 problems were found to be correlated with good quality of life. A similar pattern of correlations was found with bad quality of life. Conclusions Due to the difficulties in attaining reliable assessment of quality of life using psychometric questionnaires, the further proof of validity obtained in this study allows us to propose the re-evaluation of the role of the uniscale in measuring the quality of life of cancer patients.

Aims and background Hepatocellular carcinoma (Hcc) is the third most common cause of cancer death. The aim of this study is to examine the factors associated with improved prognosis in Hcc after liver resection. Patients and methods From September 1989 to March 2005, 134 consecutive patients had liver resection for Hcc on cirrhosis at our department. We performed 54 major liver resections and 80 limited resections. All patients enrolled in the study were followed-up three times during the first year after resection and twice the next years. Results In-hospital mortality rate was 7.4%, about 50% of these cases were Child-Pugh B patients. Morbidity rate was 47.7%, caused by the rising of ascites, temporary liver impairment function, biliary fistula, hepatic abscess, hemoperitoneum and pleural effusion. Overall survival resulted to be influenced by etiology (P = 0.03), underlying liver disease, in particular Child A vs BC (P = 0.04), Endmondson-Steiner grading (P = 0.01), the absence of a capsule (P = 0.004), the presence of more than one lesion (P = 0.02), lesion's size over 5 cm (P = 0.04), Pringle maneuver length over than 20 minutes (P = 0.03), an amount of resected liver volume lesser than 50% of total liver volume (P = 0. 03), and the relapse of Hcc (P = 0.01). Conclusions The treatment of hepatocellular carcinoma should be both the most radical to obtain the best outcome and to reduce the recurrence's rate, and the most suitable according to the patient's condition, lesion's characteristics and underlying liver disease: because of the large number of factors affecting the outcome of Hcc, unfortunately, we are still far from an agreement upon a group of criteria useful to select the best candidates for liver resection.

Published: February 2018

Aims Mounting evidence indicates that deregulation of apoptosis is involved in the mechanisms of cancer development. Integrins are cell adhesion receptors that mediate cell survival and migration. A recent study showed that unligated integrin beta 3 (ITGB3) induced apoptosis by recruitment of caspase-8. The aim of the present study was to explore the possibility that genetic alteration of the ITGB3 gene is involved in the development of human cancers possibly by inactivating the apoptosis function of ITGB3. Methods We analyzed the coding region of the cytoplasmic domain of the human ITGB3 gene for the detection of somatic mutations in 100 gastric, 90 colorectal, 100 non-small cell lung, 43 urinary bladder and 50 head-neck cancers by a polymerase chain reaction-based, single-strand conformation polymorphism. Results We found an identical ITGB3 mutation in two unrelated patient samples (one in colorectal and the other in bladder cancer). The ITGB3 mutation was a missense mutation which would substitute an amino acid (E757K). Conclusions The data suggested that the proapoptotic ITGB3 cytoplasmic domain is rarely mutated in common human cancers and may not play an important role in the development of the cancers.

Aims and Background To improve the survival of patients with aggressive non-Hodgkin's lymphoma, we evaluated a risk-adapted therapeutic approach using high-dose (HD) or conventional-dose (CD) chemotherapy (CT) for poor-risk and good-risk patients, respectively. Methods Twenty patients were treated in each group. In both groups, the first chemotherapy cycle consisted of dexamethasone, vincristine, ifosfamide, and etoposide. Thereafter, the CD or HD patients received 3 or 2 cycles of dexamethasone, vincristine, epirubicin, and cyclophosphamide, respectively, followed by 1 cycle of dexamethasone, carboplatin, and etoposide. In the HD group cyclophosphamide, epirubicin, carboplatin, and etoposide were dose-escalated by a factor of 6, 3, 3, and 3, respectively, as compared to the CD group, and autologous peripheral blood stem cells were administered after each HD-CT cycle. Results Grade III-IV toxicities were neutropenia and thrombocytopenia (100%), anemia (55%), and stomatitis (30%) in patients with HD-CT, and neutropenia (90%) in patients with CD-CT. One toxic death occurred in a patient with HD-CT. The overall response rate was 100% in HD-CT patients, including 70% complete remissions, and 80% in CD-CT patients, including 60% complete remissions. The 10-year overall survival was 55% for patients with HD-CT and 80% for patients with CD-CT. Conclusions The risk-adapted treatment approach showed tolerable toxicities and was associated with encouraging results.

Aims and Background To determine whether there is a benefit for biochemical control with adjuvant radiation therapy to the surgical bed following radical prostatectomy in patients with seminal vesicle invasion and pathologically negative pelvic lymph nodes (pT3b-pT4 pN0). Methods We retrospectively reviewed the clinical records of radical prostatectomy patients treated between 1995 and 2002. A total of 66 patients with seminal vesicle invasion were identified: 45 of these patients received adjuvant radiation therapy and 21 were observed. Radiation therapy was initiated within 4 months of prostatectomy. Median dose was 66 Gy (range, 60–70 Gy). Median follow-up from the day of surgery was 40.6 months (mean, 41.5; range, 12–99). Biochemical recurrence was defined as the first value ≥0.2 ng/ml. Results At two years, the proportion of patients free from biochemical recurrence was 80% in patients who received adjuvant radiation therapy versus 54% for those not given radiation therapy (P = 0.036). Actuarial biochemical recurrence at 5 years was 59% vs 41% for the radiation therapy and no radiation therapy groups, respectively. On univariate Cox regression model, the hazard of biochemical failure was also associated with a detectable (≥0.2 ng/ml) postsurgical prostate-specific antigen (P = 0.02) prior to radiation therapy. Pathological T stage (pT3b vs pT4), Gleason score, primary Gleason pattern and positive surgical margins were not significantly associated with biochemical recurrence. The hazard of biochemical failure was around 85% lower in the radiation therapy group than in the observation group (P = 0.002). Conclusions Data from the present series suggest that adjuvant radiation therapy for patients with seminal vesicle invasion and undetectable (≤0.2 ng/ml) postoperative prostate-specific antigen significantly reduces the likelihood of biochemical failure.

Aim and background Hepatitis B virus (HBV) and hepatitis C virus (HCV) are not only hepatotropic, but also lymphotropic viruses. Infections with these viruses induce chronic antigenicity and may stimulate clonal expansion of malignant B-cell neoplasms. Moreover, these viruses can proliferate in lymphatic structures and bone marrow. However, the relationship between lymphomas and HBV/HCV infections is not clear. In our region of the East Black Sea, Turkey (the city of Trabzon), we intended to demonstrate a relation of lymphoma and HBV/HCV infections with a case-controlled study. Methods A total of 109 patients diagnosed with lymphoma between 2002–2005 in the Black Sea Technical University Hospital was investigated. Seventy-one patients had a high-grade and 38 patients a low-grade lymphoma. Hepatitis B surface antigen (HBsAg) and anti-HCV antibodies (anti-HCV Ab) were screened. The control group consisted of patients (n = 551) from other departments with diagnoses other than lymphoma. Results HBsAg was 3.7% and anti-HCV Ab positivity was 2.8% in lymphoma patients, compared with control of 5.3%, 5.1%, respectively. There was no statistically significant difference between two groups ( P = 0.7, OR = 0.69, 95% CI, 0.20–2.10; P = 0.4, OR = 0.53, 95% CI, 0.13–1.86, respectively). Conclusion Our findings suggest that the incidence of HBV and HCV infections in lymphoma patients is no different than that of nonlymphoma patients. Therefore, no direct correlation can be deduced between lymphoma and HBV-HCV infections in our East Black Sea region of Turkey.

Aims and background The purpose of the study was to evaluate the outcome of metastatic colorectal cancer patients treated, as first line, with 5-fluorouracil bolus/leucovorin + oxaliplatin, in terms of response, progression-free and overall survival. Materials and methods A retrospective cohort of consecutive metastatic colorectal cancer patients, treated from 2003 to 2006, was identified and analyzed. All patients, without a central venous device, were treated with oxaliplatin + 5-fluorouracil and leucovorin. Results Twenty-five metastatic colorectal cancer patients were treated. No 3–4 grade toxicity was observed. Five of 23 patients achieved a partial response: one of them resulted in a complete response after radiofrequency and another one after surgery. Fifteen of 23 patients had stable disease (one underwent radical surgery after chemotherapy, obtaining a complete remission) and 3 had progressive disease. Median progression-free survival was 7.2 months, and median overall survival was 30 months. Conclusions Based on this case-series study, the regimen seems to offer a good control of disease (86.9%) and can be considered as an alternative choice for patients who cannot receive continuous infusion.

Aim To assess the role of breast ultrasonography as a complement to negative mammography in radiologically dense breasts. Material and methods Out of a total series of 49,044 consecutive mammograms reported as negative in asymptomatic women, 25,665 (52.3%) were coded as dense (BI-RADS D3–4) and ultrasonography was recommended. Due to organizational problems, ultrasonography was performed immediately or within 1 month only in 5,227 cases, representing the study series. Results Two cancers were detected at immediate ultrasonography (0.03%). The cancer detection rate in women aged 40–49 and 50–69 years was 0.002% and 0.07%, respectively. The benign biopsy rate was 0.5% for core biopsies and 0.02% for surgical biopsies. The cost per ultrasonography-assessed woman was € 56.05, whereas the cost per additional mammographically occult but ultrasonography-detected cancer was € 146,496.53. The mammograms of the 2 cancer cases underwent blind review by an expert reader and were confirmed as negative. Discussion Our findings show a low cancer detection rate, substantially lower compared to other clinical studies of ultrasonography in dense breasts, though in accordance with preliminary evidence from an Italian randomized clinical trial within a population-based screening program. The policy of adding ultrasonography to negative mammography in dense breasts seems to have very limited cost-effectiveness, and should not be adopted in routine practice before results of ongoing clinical trials are available.

Aims and background The purpose of the study was to identify prognostic factors that affect survival following bone metastasis in breast cancer patients with first metastases in the skeletal system. Methods and study design We analyzed retrospectively the data of 248 metastatic breast cancer patients whose first distant metastasis was in the skeleton. Results The median age of the patients at diagnosis was 46 years (range, 23–76). Nearly half of the patients were premenopausal (52.4%). The median disease-free survival was 24 months. For most of the patients (221), bone was the sole first metastatic site, and the disease remained confined to the bone in 99 of them. The remaining patients (n = 27) had both bone and visceral metastasis at the time of first relapse. One hundred and fourteen of the patients (46%) had died by the time of analysis. With the median follow-up of 50.5 months from diagnosis, median survival after bone metastasis was 32 months. In univariate analyses, statistically significant predictors for survival after bone metastasis were axillary lymph node status, T stage of disease, hormone receptor status of the primary tumor, the presence of lymphovascular invasion, involvement of skin, the presence of additional nonosseous metastatic sites at the time of bone relapse, and disease-free interval. In multivariate analyses, the presence of additional non-osseous metastatic sites at the time of bone relapse, T stage of disease, hormone receptor status of the primary tumor, and the presence of lymphovascular invasion were found to be significant independent prognostic factors. Conclusions In the result of study, for patients with breast cancer, survival following bone metastasis is affected by secondary prognostic factors such as disease-free interval and extent of metastasis besides primary prognostic factors related to the primary tumor.

Published: February 2018

Penetration and abscess formation in an adjacent parenchymal organ as presentation of a colon cancer is very uncommon. We report a rare case of pyogenic liver abscess as the first manifestation of an infiltrative and penetrating hepatic flexure colon carcinoma without liver metastases. A 50-year-old woman was admitted with right abdominal pain, fever and chills. The initial diagnosis was a pyogenic liver abscess. Subsequent CT scan and colonoscopy evidenced a hepatic flexure colon cancer abscessed within segment 6 of the liver. Eight months after a right colectomy and liver resection there was no evidence of disease. The occurrence of a pyogenic liver abscess should raise the suspicion of a silent colon cancer.

Published: February 2018

Aims and background Primary bilateral adrenal non-Hodgkin's lymphoma is an extremely rare entity. Only 44 cases have been reported in the literature. The most common presenting symptoms are abdominal pain, fever, asthenia, constipation, weight loss or typical symptoms of adrenal insufficiency, hypertension, darkening of skin, orthostatic hypotension or an addisonian crisis. Methods The case is presented of a 57-year-old man suffering from primary bilateral adrenal lymphoma with symptoms of adrenal insufficiency syndrome associated with bilateral, stabbing lumbar pain and a palpable mass on the left side. Laboratory tests revealed a considerable increase in lactate dehydrogenase levels, adrenal insufficiency, and high corticotropin levels. Results Abdominal CT scan showed two large adrenal masses. A CT-guided fine needle aspiration biopsy revealed a large B-cell non-Hodgkin's lymphoma. Combination chemotherapy according to the CHOP protocol with cyclophosphamide, doxorubicin, vincristine and prednisolone was initiated, which caused a slight reduction in size of the two adrenal masses. The patient underwent a bilateral adrenalectomy with almost complete excision of the tumors. Replacement therapy with cortisone acetate was initiated postoperatively. Adjuvant combination chemotherapy according to the CHOP protocol was started but renal failure gradually emerged and the treatment could not be completed. The patient died seven months after surgery due to acute bronchial pneumonia and progression of disease. Conclusions Primary bilateral adrenal non-Hodgkin's lymphoma mainly affects adult men. Diagnosis is based on histological examination. Whether associated or not with radiotherapy, chemotherapy is the most recommended treatment. Surgery, where possible, seems to lead to an increase in survival rates, but it is not possible to draw any definite conclusions on its effectiveness as yet.

Published: February 2018

Background Mammary phyllodes tumor is an uncommon stromal-epithelial neoplasm with a reported incidence of 0.3% to 0.5% of female breast tumors. Sudden, rapid growth of a mammary phyllodes tumor with intratumoral hemorrhage was noted in a 45-year-old woman after menstrual induction with progesterone and norethindrone acetate. This case is presented here to highlight the possibility of such an onset of phyllodes tumor in order to facilitate its prompt diagnosis. Case presentation A 45-year-old woman suffered from missed periods for 2 months and received progesterone for menstrual induction. After treatment, rapid enlargement of her left breast was noted. Tracing the history of the patient, we found that she had already felt an about 3 cm painless lump in her left breast 5 months before this episode. Sonography of the left breast showed a large cystic lesion with some echogenic content and about 150 mL of old blood was obtained by aspiration. Surprisingly, follow-up breast sonography 3 weeks later revealed a large irregular solid mass and a small amount of peripheral cystic content with markedly increased vascularity. Surgery was suggested. A large encapsulated mass consisting of heterogeneous yellow soft tissue and a cystic component measuring 10 × 8 cm was totally excised. Microscopically, the sections revealed branching and cystically dilated glands lined by cuboidal to columnar epithelial cells in a myxoid hypercellular fibroblastic stroma with hyperchromatic nuclei and frequent mitotic figures. The final histological diagnosis was malignant phyllodes tumor. Conclusion Progesterone for menstrual induction may cause rapid growth of a phyllodes tumor with resultant internal hemorrhage. Only with the awareness of this entity can a prompt diagnosis be made and optimal treatment be given.
