Feline colonic adenocarcinoma is a locally invasive, highly metastatic tumor that is most often treated with wide surgical excision (subtotal colectomy) and systemic chemotherapy either with or without nonsteroidal anti-inflammatory medications. In this retrospective study, the outcome of subtotal colectomy and adjuvant carboplatin in 18 client-owned cats is described. The median carboplatin dose was 200 mg/m2 (range, 200–254 mg/m2) q 4 wk with a median of five doses/cat (range was two to seven doses/cat). Limited toxicities were noted. Positive prognostic factors for the disease-free interval included cats that had weight loss as a presenting sign (P < 0.036) and negative prognostic factors for median survival included nodal and distant metastasis (178 versus 328 days and 200 versus 340 days, respectively). The median disease-free interval was 251 days (range, 37–528 days) and the median survival time was 269 days (range, 40–533 days). Subtotal colectomy and adjuvant carboplatin is a safe and potentially effective treatment for cats with colonic adenocarcinoma.

CONTEXT: Search of tumors markers that allow treatment with higher survival rates, and indicate the response to treatment and recurrence of cancer OBJECTIVE: To analyze the immunoexpression of the proteins p53, bcl-2 and Ki-67 in colorectal adenocarcinoma and correlate them with the clinical-pathological prognostic factors. METHOD: Tissue microarray paraffin blocks were made from colorectal adenocarcinoma tissue resected from 82 patients who had undergone surgery but not chemotherapy or radiotherapy, at "Hospital São Paulo", São Paulo, SP, Brazil, between 2002 and 2005. Thin sections (4 µm) were subjected to immunohistochemical reactions, and immunoexpression staining scores were obtained. The scores were correlated with the degree of cell differentiation, staging, disease-free interval, recurrence, survival and specific mortality. The study variables were analyzed using the chi-square and Kaplan-Meier tests to investigate associations with the markers. The significance of the differences between the curves of the disease-free interval and survival was analyzed using the Logrank and Wilcoxon tests. RESULTS: The immunohistochemical expression of p53 was positive in 70 tumors (85.4%) and negative in 12 (14.6%). The expression of bcl-2 was positive in 26 (31.7%) and negative in 56 (68.3%). The expression of Ki-67 was positive in 62 (75.6%) and negative in 20 (24.4%). There was no statistically significant correlation between the expressions of these markers separately or in conjunction, in relation to the degree of cell differentiation, staging, disease-free interval, survival and specific mortality. In relation to recurrence, there was a statistically significant correlation with positive expression of Ki-67 (P = 0.035). CONCLUSION: The immunohistochemical expression of Ki-67 in colorectal cancer is associated with recurrence of this disease.

e15107 Background: Pulmonary is the second common metastastic site of CRC with a good survival after metastasectomy, however the general situation of pulmonary metastases from CRC has received little attention, especially for unresectable ones. The aim of this study was to determine factors that may influence survival and disease free interval from primary radical surgery to pulmonary metastases (DFI). Methods: From 01/2000 to 11/2008, a total of 206 pts with pulmonary metastases (colon72, rectal ca131, 3 unknown) were collected retrospectively and the clinical data were analyzed using Kaplan-Meier survival curves, univariate and multivariate analysis. Results: 128 pts (62.1%) had lung disease as the first metastatic site and 33 pts (26.7%) had synchronous liver involvement. Only 17 patients (8.3%) followed pulmonary metastatic resection, and others underwent palliative medical treatment including the chemotherapy and intervention. Median survival was 16.0 months (range 12.240–19.760) with a 18% 5-year survival. Of the totally 160 patients who had synchronous pulmonary metastases after radical primary tumor surgery, the mDFI was 20 months (range 16.738–23.262) months. Rectal cancer had a high chance (65%) for lung recurrence with longer DFI (21 vs 14 mo, P=0.02), but no difference of survival was shown compared to colon cancer. Factors that significantly predicted a poor prognosis on univariate analysis included vessel invasion (P=0.022) and high T stage (P=0.009), but neither of them was the independent prognostic factors after multivariate analysis. The factors influencing the DFI of metachronous pulmonary metastases included primary tumor site, pathological morphology, tumor infiltration stage and regional lymph node stage (P<0.05). There was a trend of better survival of patients receiving resection surgery after pulmonary metastases than receiving chemotherapy alone though no statistical significant was reached (mOS:34 vs 16 mo, P=0.125). But to patients who receiving metastatic site resection, chemotherapy after surgery improved the survival (P=0.042). Conclusions: No independent prognostic factors of survival had been found. The invasive tumor with high stage may have a shorter disease free interval of pulmonary metastases after primary surgery. No significant financial relationships to disclose.

Objective. To investigate the efficacy of surgery in the treatment of metastatic renal cell carcinoma (mRCC) and to identify prognostic factors. Methods. A single center retrospective study of 96 patients with mRCC from December 2004 to August 2013. Results. The median follow-up time was 45 months. Thirty-one (32.3%) of the patients received complete resection of metastatic sites, 11 (11.5%) of the patients underwent incomplete resection of metastatic sites, and 54 (56.3%) of the patients received no surgery. In the univariate Kaplan-Meier analysis, the median overall survival times of the three groups were 52 months, 16 months, and 22 months, respectively (p<0.001). The difference in the overall survival time was statistically significant between complete resection and no surgery groups (HR = 0.43, p=0.009), while there was no significant difference between the incomplete metastasectomy and no surgery groups (HR = 1.80, p=0.102). According to the multivariate Cox regression analysis, complete metastasectomy (HR = 0.49, p=0.033), T stage > 3 (HR = 1.88, p=0.015), disease free interval <12 months (HR = 2.34, p=0.003), and multiorgan involvement (HR = 2.00, p=0.011) were significant prognostic factors. Conclusion. In the era of targeted therapy, complete metastasectomy can improve overall survival. Complete metastasectomy, T stage > 3, disease free interval <12 months, and multiorgan involvement are independent prognostic factors.

Cutaneous hemangiosarcoma (HSA) has been infrequently reported in dogs and cats. Medical records of 18 cats diagnosed with cutaneous HSA were reviewed. Age at the time of diagnosis, breed, sex, tumor location, tumor size, treatment type, survival time, disease-free interval, and cause of death were evaluated. Aggressive surgical excision of the tumor was attempted in 10 cats. A complete surgical excision was achieved in five of the 10 cats. Median survival times were statistically longer in cats that underwent surgery versus cats that did not. Cats with cutaneous HSA treated with aggressive surgical excision of their tumors may have a good long-term prognosis.

Abstract OBJECTIVES Atypical carcinoids are neuroendocrine neoplasms of intermediate degree and low frequency. The aim of this study is to analyse their clinical characteristics and the importance of different histopathological factors in their prognosis. METHODS Multicentre cooperative group EMETNE prospectively reviewed 153 patients operated on between 1998 and 2016 with diagnosis of atypical carcinoids. Clinical variables and histopathological features were assessed. RESULTS Mean age was 54.36 years, similar for both genders. Concerning pathological study, mean tumour size was 31.7 mm. Rosettes were presented in 17% of the cases and tumoural necrosis in 23.3%. The cell proliferation factor Ki-67 index was 10.7%. The 2- and 5-year overall survival rates were 95.8% and 88.9%, respectively. In the univariate study, statistically significant differences in survival were found for each of the categories of T, N and M factors. Mitotic index and quantification of expression of Ki-67 showed influence in overall survival, although without statistical significance. In the multivariate analysis, factors N, M and mitotic index behaved as independent prognostic factors related to survival. Median disease-free interval in the series was 163.35 months. In cases with loco-regional recurrence, 53% had positive hiliar or mediastinal nodal involvement at the time of the surgery. In the univariate analysis, we observed statistically significant differences in disease-free interval in patients with nodal involvement (P = 0.024) and non-anatomical resections (P = 0.04). Histological characteristics showed no statistically significant differences in disease-free interval. CONCLUSIONS Lymph node involvement, the development of distant metastasis and mitotic index, more than Ki-67 determination, were shown as independent prognostic factors related to survival of these patients.

PURPOSE: To analyze the expression of metalloproteinase-1, metalloproteinase-7 and vascular endothelial growth factor (VEGF) in colorectal adenocarcinoma, and to correlate these with the clinical-pathological prognostic factors. METHODS: Tumor tissue from 82 patients was fixed in formalin and embedded in paraffin blocks. These samples were analyzed by means of the streptavidin-biotin immunohistochemical method, using the tissue microarray technique. Marker positivity was evaluated using categorical scores that determined cutoff percentages of stained tumor cells. Protein tissue expression was correlated with the variables of degree of cell differentiation, staging, disease-free interval, recurrence, survival and specific mortality. The Fisher exact and Kaplan-Meier tests were used to assess associations between the markers and the study variables. The log-rank and Wilcoxon tests were used to assess the significance of differences between curves of disease-free interval and survival. RESULTS: All tumors were positive for metalloproteinase-1; 50 (61%) were positive and 32 (39%) were negative for metalloproteinase-7; and 60 (74.1%) were positive and 21 (25.9%) were negative for VEGF. Correlation of marker expression, both in groups and individually, did not show statistical significance in relation to the degree of cell differentiation, staging, disease-free interval, survival or specific mortality. Recurrence showed a statistically significant correlation with positive expression of the three markers, when analyzed as a group (p = 0.038). CONCLUSION: The associated expression of metalloproteinase-1, metalloproteinase-7 and VEGF in colorectal adenocarcinoma is related to the incidence of disease recurrence.

Objectives The main aim of the study was to establish response, disease-free interval (DFI) and overall survival of cats with nasal planum squamous cell carcinoma (SCC) treated with Sr90 plesiotherapy. A secondary aim was to determine whether a fractionated protocol is more effective than a single-dose protocol in terms of response, DFI and overall survival. The third aim was to evaluate whether we can identify prognostic factors that influence overall survival. Methods This was a retrospective study that included cats with a diagnosis of nasal planum SCC treated with Sr90 plesiotherapy at a single institution. Results Seventy-four cats were included in the study. Thirty-two were treated with a fractionated protocol and 42 with a single-dose treatment. Sr90 plesiotherapy was able to induce complete response in 74% of cats with nasal planum SCC. The median DFI was 780 days (95% confidence interval [CI] 383–1177), with 17% of cats experiencing local recurrence. The overall survival for all cats was 1039 days (95% CI 55–1528). The DFI of cats treated with the fractionated Sr90 was significantly longer compared with the single-dose treatment, whereas response and overall survival were not statistically different. Other prognostic factors that influenced the overall survival were early-stage disease, absence of concurrent problems and complete response to the treatment. Acute and long-term toxicity associated with the treatment were minimal and the aesthetic outcome was pleasing in almost all cases. Conclusions and relevance Strontium plesiotherapy is a safe and effective treatment of nasal planum SCC in cats.

The aim of this study is to identify the impact of various prognostic factors on survival in patients with recurrent carcinoma of the uterine cervix. Fifty-two patients who were treated with platinum-based chemotherapy for recurrent or metastatic disease were retrospectively evaluated. Twenty-seven patients (90%) had received pelvic radiation as primary treatment.Out of 45 evaluable patients, two (4.4%) had complete response (CR), three (6.7%) had a continuous CR after additional surgical treatment and irradiation. Five patients (11.1%) had partial response (PR). The majority of patients had progressive response to treatment (22 patients, 48.9%). After a median follow-up period of 19 months, 31 patients (60%) had died. Progression-free survival after initial diagnosis was observed to have a significant association with response to chemotherapy for recurrent disease (Fisher two-sided P = 0.027). The median survival duration for relapsed disease was 11.8 months. Those with a longer disease-free interval (8 months vs. ≤ 8 months) from initial diagnosis to first recurrence and reponse to chemotherapy had a tendency for a longer survival duration after relapse by univariate analysis. Multivariate analysis revealed that progressive response to chemotherapy (P = 0.002, HR = 4.6) and recurrence within the previously irradiated field (P = 0.04, HR = 2.7) were significant independent prognostic factors for a shorter time to progression after recurrence. Furthermore, advanced stage at presentation (P = 0.001, HR = 3.0) and a short disease-free interval after primary treatment (<8 months, P = 0.003, HR = 3.4) were determined as independent prognostic factors with a significant negative influence on progression-free survival and overall survival from initial diagnosis, respectively.The use of toxic and expensive combinations for the treatment of recurrent cervical cancer patients should be well balanced against potential hazards. Based on our data, less toxic regimens would be more feasible in patients who present with advanced disease at initial diagnosis, or those that experience recurrence within the previously irradiated field after a progression-free interval of less than 8 months.

ObjectiveThe para-aortic lymph nodes are one of the most common sites in recurrent cervical cancer. However, treatment strategies for para-aortic lymph node recurrence have not yet been established.This study aimed to evaluate the prognostic factors and treatment outcomes in patients with para-aortic lymph node recurrence after curative radiotherapy for cervical cancer.MethodsWe retrospectively reviewed patients who developed para-aortic lymph node recurrence following curative radiation therapy for cervical cancer from January 2001 and December 2014 at the Samsung Medical Center. Prognostic factors for overall survival after recurrence were analyzed by univariate and multivariate analyses.ResultsA total of 67 patients were included in the analysis. After a median follow-up of 24.0 months (range 4–155), the 3-year overall survival rate was 42.7%. 32 patients had isolated para-aortic lymph node recurrence (group 1), 21 patients had para-aortic lymph node recurrence combined with other lymph node recurrence (group 2), and 14 patients developed para-aortic lymph node recurrence with distant organ metastasis (group 3). The 3-year overall survival rates in groups 1, 2, and 3 were 60.8%, 42.1%, and 7.7%, respectively (p<0.001). In multivariate analysis, histologic type of squamous cell carcinoma (p=0.028), non-symptomatic recurrence (p=0.024), isolated para-aortic lymph node recurrence (p=0.008), and disease-free interval (p=0.008) were significant factors for survival. Among the patients with isolated para-aortic lymph node recurrence, survival rates differed significantly according to disease-free interval; the 3-year overall survival in patients with disease-free interval ≥12 months and disease-free interval <12 months was 69.6% and 37.5%, respectively (p<0.001).ConclusionsIn patients with para-aortic lymph node recurrence from cervical cancer, histologic type, presence of symptoms, extent of disease, and disease-free interval were the prognostic factors for survival. Patients with isolated para-aortic lymph node recurrence with disease-free interval ≥12 months had higher survival outcomes at 3 years.
