Acting primarily through its specific G protein-coupled receptor termed FPr, prostaglandin (PG) F2α induces regression of the corpus luteum (CL) at the end of a non-fertile oestrous cycle. This study was aimed at cloning a full-length cDNA for FPr and determining its expression and protein concentrations during different stages of CL development in the water buffalo. Serum progesterone and StAR expression were determined to establish temporal relationships between indices of steroidogenesis and changes in FPr expression at different stages of CL development. In contrast to the dairy cow, the stage IV CL (day 20 of the oestrous cycle) did not appear to be functionally regressed in the buffalo. Molecular cloning of a cDNA encoding the buffalo FPr yielded a full length 2193 bp FPr cDNA containing a single open reading frame encoding a 362 amino acid protein with seven putative membrane-spanning domains. The deduced buffalo FPr amino acid sequence possesses a high degree of identity with the other mammalian homologues. Steady state concentration of buffalo FPr transcript increased (P > 0.05) from stage I to stage II/III, and declined at 18 h post PGF2α injection. The FPr concentration expressed as fmol/μg of plasma membrane protein showed an increase (P > 0.05) from stage I (1.98 ± 0.10), through stage II/III (2.42 ± 0.48) to stage IV (2.77 ± 0.18). High affinity FPr was observed in stage I (Kd 4.86 nmol) and stage II/III (Kd 6.28 nmol) while low affinity FPr (Kd 19.44 nmol) was observed in stage IV. In conclusion, we have cloned a full length FPr cDNA from buffalo cow CL and observed that FPr mRNA expression, receptor number and affinity did not vary significantly (P > 0.05) within the luteal phase of the oestrous cycle.

Gastric cancer is the third most common cause of cancer deaths worldwide. Despite evidence-based recommendation for treatment, the current treatment patterns for all stages of gastric cancer remain largely unexplored. This study investigates trends in the treatments and survival of gastric cancer. The National Cancer Database was used to identify gastric adenocarcinoma patients from 2004–2016. Chi-square tests were used to examine subgroup differences between disease stages: Stage I, II/III and IV. Multivariate analyses identified factors associated with the receipt of guideline concordant care. The Kaplan–Meier method was used to assess three-year overall survival. The final cohort included 108,150 patients: 23,584 Stage I, 40,216 Stage II/III, and 44,350 Stage IV. Stage specific guideline concordant care was received in only 73% of patients with Stage I disease and 51% of patients with Stage II/III disease. Patients who received guideline consistent care had significantly improved survival compared to those who did not. Overall, we found only moderate improvement in guideline adherence and three-year overall survival during the 13-year study time period. This study showed underutilization of stage specific guideline concordant care for stage I and II/III disease.

Bladder Cancer (BC) is a common disease worldwide. Chronic inflammation is one of the key mechanisms for the development of BC. This study enrolled 40 patients. Preoperative plasma levels of IL-1β, IL-4, IL-6, IL-10, IL-12β, TNF-α and IFN-γ were determined by ELISA. In our study, we observed diverse changes in the levels of cytokines in patients with BC Stage I, II, III and IV. The levels of IL-1β was increased for stage I, stage II, and stage III. The level of TNF-α was increased for stage II, stage III, stage IV. The levels of IL-4, IL-6, IL-10 and IL-12β were increased in patients with stage III and IV only. The levels of IFN- γ declined for stage II, stage III and stage IV with the lowest levels in patients with Stage IV. In our study, we investigated alteration in levels of Th-1 and Th-2-like cytokine profile, but some deficiency in Th1- status discovered in patients with BC.

PURPOSE: Previous studies demonstrated that chemotherapy with either cisplatin, vincristine, and fluorouracil (regimen A) or cisplatin and continuous infusion doxorubicin (regimen B) improved survival in children with hepatoblastoma. The current trial is a randomized comparison of these two regimens. PATIENTS AND METHODS: Patients (N = 182) were enrolled onto study between August 1989 and December 1992. After initial surgery, patients with stage I–unfavorable histology (UH; n = 43), stage II (n = 7), stage III (n = 83), and stage IV (n = 40) hepatoblastoma were randomized to receive regimen A (n = 92) or regimen B (n = 81). Patients with stage I–favorable histology (FH; n = 9) were treated with four cycles of doxorubicin alone. RESULTS: There were no events among patients with stage I-FH disease. Five-year event-free survival (EFS) estimates were 57% (SD = 5%) and 69% (SD = 5%) for patients on regimens A and B, respectively (P = .09) with a relative risk of 1.54 (95% confidence interval, 0.93 to 2.5) for regimen A versus B. Toxicities were more frequent on regimen B. Patients with stage I-UH, stage II, stage III, or stage IV disease had 5-year EFS estimates of 91% (SD = 4%), 100%, 64% (SD = 5%), and 25% (SD = 7%), respectively. Outcome was similar for either regimen within disease stages. At postinduction surgery I, patients with stage III or IV disease who were found to be tumor-free had no events; those who had complete resections achieved a 5-year EFS of 83% (SD = 6%); other patients with stage III or IV disease had worse outcome. CONCLUSION: Treatment outcome was not significantly different between regimen A and regimen B. Excellent outcome was achieved for patients with stage I-UH and stage II hepatoblastoma and for subsets of patients with stage III disease. New treatment strategies are needed for the majority of patients with advanced-stage hepatoblastoma.

Between 1962 and 1986, a total of 338 consecutive newly diagnosed children and adolescents with non-Hodgkin's lymphomas (NHLs) were evaluated and treated at St Jude Children's Research Hospital (SJCRH). Median follow-up is 6.6 years (range, 1.8 to 23 years). The patients ranged in age from 7 months to 21 years (median, 10 years), and 71% were males. All cases were staged (I to IV) by a clinical staging system. Eighteen percent were stage I, 21% stage II, 43% stage III, and 18% stage IV. Cases frankly leukemic at diagnosis (ie, greater than 25% marrow blasts) were excluded from the analysis. Pathologic material from all cases was reviewed and classified according to the Working Formulation. The histologic distribution of cases was as follows: 38.8% diffuse small non-cleaved cell (undifferentiated, Burkitt's and non-Burkitt's); 26.3% diffuse large-cell, mainly immunoblastic; 28.1% lymphoblastic; and 6.8% other. Treatment policy evolved over time to a stage- and histology-specific strategy for treatment assignment, and overall results significantly improved by era from 37% (+/- 5%) 2-year event-free survival (EFS) for patients treated before 1975 to 77% (+/- 4%) since 1978. By univariate and multivariate Cox regression analyses, the era of treatment (hence, the protocol-specific treatment itself), the stage, and the log of the initial serum lactic dehydrogenase (LDH) emerged as the most powerful prognostic indicators, while histology per se was not significantly related to outcome. For the 154 patients treated since 1978, the 2-year EFS by stage was 97% (+/- 3%) for stage I, 86% (+/- 6%) for stage II, 73% (+/- 6%) for stage III, and 47% (+/- 11%) for stage IV (P less than .0001). Compared with our previous experience, we conclude that the cure rate of childhood NHL has doubled in the last decade with modern management.

Single-incision laparoscopic surgery (SILS) has been developed with the aim to further reduce the invasiveness of conventional laparoscopy. Our experiences with more than 300 consecutive patients with SILS for colon cancer are reviewed, and its outcomes are evaluated to determine the midterm clinical and oncologic safety of SILS for colon cancer in a community hospital. A single surgeon's consecutive experience of SILS for colon cancer is presented. Three hundred and eight patients were treated with the SILS procedure for colon cancer between December 2010 and March 2015. Data were analyzed according to intention to treat. Of these 308 patients, 19 (6.2%) were converted to laparotomy. Intraoperative injury occurred in five patients. Postoperative complications occurred in 19 patients (6.2%). The 2-year relapse-free survival rates of patients with Stage I, Stage II, and Stage III were 97.8, 92.2, and 80.4 per cent, respectively, and the 2-year overall survival rates of patients with Stage I, Stage II, Stage III, and Stage IV were 100, 95.7, 93.0, and 74.4 per cent, respectively. Our initial experiences showed that SILS colectomy for cancer can be performed safely and with good short-term oncologic outcomes by a skilled surgeon.

One hundred forty-eight patients with newly diagnosed follicular lymphoma were treated over a 12-year period. Twenty-two patients received radiotherapy for stage I and II disease, followed by adjuvant chemotherapy in 14 patients. One hundred thirteen were treated at presentation with short courses of chemotherapy, most often with single-agent chlorambucil for bulky stage II and stages III and IV disease. Thirteen patients were managed expectantly until there was evidence of disease progression. The median survival was 9 years. Patients treated with radiotherapy for stage I and II disease had an 83% relapse-free survival, but those with bulky stage II or stages III and IV disease treated with chemotherapy pursued a remitting and relapsing course with a 70% response rate at initial and subsequent retreatments, but a median duration of remission of 4 years in stage III and 1 year in stage IV disease (P = .041). Patients were observed in relapse and retreatment was administered as appropriate, once every 33 months on average. Poor prognosis patients could be identified by a combination of the presentation characteristics: B symptoms, hepatosplenomegaly, anemia, and abnormal liver function. These factors predicted a poor response to treatment and correlated with a short survival. Histologic subgroups were not associated with differences in survival, but transformation to a diffuse high-grade lymphoma was observed in 23 of the 72 patients (32%) at risk, with a median follow-up of 6 years and 6 months, and was associated with a very poor prognosis. The present treatment strategy has proved successful for most patients with localized disease and those older patients with indolent small volume disseminated follicular lymphoma. New approaches are being investigated for the younger poor prognosis patients.

Abstract [Background] Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma, characterized by the overexpression of cyclin D1 derived from t(11;14)(q13;q32) and poor prognosis. Most MCLs show nodal presentation, but also accompany extranodal involvement, such as bone marrow, peripheral blood or gastrointestinal tract. As a result, many MCLs present with advanced stage disease. Since only a small portion of patients show limited-stage disease, minimal data exist on treatment of patients diagnosed with limited stage disease. Nevertheless, the treatment strategy of MCL is recommended according to the clinical stage of limited- (stage I or non-bulky II) vs. advanced-stage, as well as other types of lymphoma. [Patients and methods] We recently collected 633 patient data of MCL (Chihara, et al. Ann Oncol 2015). Information of clinical stage was available in 626 patients. The patient data were retrospectively analyzed the by the clinical stage at initial presentation. [Results] The clinical stage was I in 24 patients (4%), II in 33 (5%), III in 70 (11%), and IV in 499 (80%). Only one patient presented with bulky stage II. Detailed demographic information by the clinical stage are listed in Table. Age and sex were not significantly different by clinical stage. Limited stage patients were associated with better performance status (PS), less B symptoms, no extranodal involvement, and lower lactate dehydrogenase (LDH) level and white blood cell (WBC) count. Most patients in any stage were treated with cytotoxic chemotherapy, but more patients in limited stage received radiotherapy. The proportion of high-dose cytarabine (HDCA)-containing regimen over CHOP/CHOP-like was higher in advanced stage patients. Complete and overall response rates were 92% and 96% in stage I, 58% and 94% in stage II, 66% and 86% in stage III, and 52% and 82% in stage IV, respectively (P = 0.02). However, the higher response rate in limited stage patients did not translate into better prognosis. The median survival was 11.0 years in stage I, 13.4 years in stage II, 11.5 years in stage III, and 5.6 years in stage IV (Figure). The prognosis was not significantly different among patients with stage I, II, and III (P = 0.33). [Conclusion] Prognosis of limited-stage MCL was almost similar to that of stage III MCL. Although the present study includes several limitations including a retrospective nature and limited number of patients, prognosis of patients with limited-stage MCL was not satisfactory. The significance of radiotherapy, as well as the optimal choice of chemotherapy, for limited-stage MCL needs re-evaluation. Table Table. Figure Figure.

e22228 Background: Breast cancer (BC) is the most common malignancy in women in Lebanon. Triple negative (TN) phenotype is known to be associated with an increased likelihood of recurrence and death. The purpose of this study is to determine the incidence, characteristics and survival of TN BC patients in a Medical Oncology department in a University Hospital in Lebanon. Methods: We retrospectively reviewed the pathology of all women with breast cancer that were seen in our institution between 1997 and 2008. TN BC patients (pts) were defined as those that were negative for all 3 receptors (estrogen, progesterone and HER2neu on immunohistochemistry). Pts' characteristics and survival of TN women were analyzed. Results: Of the 1599 breast cancer pts, 155 (9.7%) had a triple negative phenotype. Median age was 52 years. A positive family history of breast/ovarian cancer was found in 15 pts (10%). Pathology studies showed: invasive ductal carcinoma component in 138 pts (89%), pure medullary carcinoma in 7 pts (5%), pure invasive lobular carcinoma in 6 pts (4%), pure mucinous carcinoma in 3 pts (2%) and epidermoid carcinoma in 1 pt (1%). A grade III was found in 98 of specimens (63%). Twenty-six pts (17%) presented with stage I, 73 (47%) with stage II, 37 (24%) with stage III and 19 (12%) with stage IV. Twelve percent had inflammatory breast cancer. After a median follow up of 17 months (mths), 43 pts had relapsed (5 stage I, 18 stage II and 20 stage III). The most common sites of relapse were brain (in 20 % of cases), lungs (in 20% of cases) and bone (in 11% of cases). Five- year disease free survival and 5-year overall survival were respectively 75% and 88% for stage I, 58% and 72% for stage II and 40% and 63% for stage III. Adjuvant therapy was administered to 96% of pts among which a taxane-based regimen was used in 38% of cases . Median survival for stage IV was 19 mths with a first line taxane-based regimen used in 50% of cases. Conclusions: The incidence of TN BC in Lebanon is similar to that described in the literature. It has an aggressive course. Focus on understanding the biology of this particular BC subtype is essential for determining targets for future therapeutic options. No significant financial relationships to disclose.
