AbstractGenetic and non-genetic factors affecting survival during the post-weaning period from 3 to 12 months of age were assessed in 823 kids (217 Black Bengal, 410 Jamunapari × Black Bengal and 196 Beetal × Black Bengal) born during 1981-86. The overall survival rates during 3 to 6 and 6 to 12 months of age were 79·22 (s.e. 4·06) and 82·02 (s.e. 5·49)% respectively. Variation in survival rate during 3 to 6 months of age was significant due to season of their birth (P < 0·01) and birth weight (P < 0·05). Survival rate during 6 to 12 months of age varied due to genetic group (P < 0·01), sex (P < 0·05) and birth weight (P < 0·05). Type of birth (litter size), dam's weight at kidding and filial generation had no significant effect on survival rate during the post-weaning period. Birth weight of kids had a positive linear relationship with their survivability during post-weaning period. Summer-born kids had significantly lower survival rates from 3 to 6 months of age compared with those born in the winter and monsoon periods. Heritability estimates for survival rates during the post-weaning period were not significantly different from zero.

ABSTRACTThe present study was carried out on 1243 kids (379 Black Bengal; 568 Jamunapari × Black Bengal and 296 Beetal × Black Bengal) born between 1981 and 1986. Data were analysed to study the influence of genetic group, sex, season of birth, type of birth, birth weight, dam's weight at kidding, filial generation and parity of dam (as covariate) on survivability of kids during the pre-weaning period (0 to 90 days of age). The overall survival rates during 0 to 15, 16 to 30, 31 to 60, 61 to 90 and 0 to 90 days of age were 81·68 (s.e. 2·89), 95·55 (s.e. 2·00), 90·77 (s.e. 2·33), 93·31 (s.e. 2·59) and 69·94 (s.e. 3·65) % respectively. Variation in survival rates from 0 to 15 days of age was significant due to genetic group (P < 0·01), birth weight (P < 0·01), dam's weight at kidding and parity of dams as a covariate (P < 0·05). Season of birth (P < 0·05), weight of kids (P < 0·01) and dam's weight at kidding (P < 0·01) had significant effects on survival rate during 0 to 90 days of age. Sex and type of birth had no significant effect on survival rates. The interaction effects of genetic groups with season of birth and sex on pre-weaning survival rates were not significant in all ages except the effect between genetic group and sex during 31 to 60 days of age. An improvement in survival rates during the period of study was noticed with the increase in filial generation number from Fj to F3, although the difference was not significant except from 61 to 90 days of age (P < 0·05). Birth weight of kids had a positive linear relationship with survivability during the pre-weaning period. Summer-born kids had a significantly lower survival rate than those born in the winter and monsoon periods from 16 to 30, 61 to 90 and from 0 to 90 days of age. A negative linear relationship was observed between dam's weight at kidding and survival rates of kids from 0 to 90 days of age except the 25 to 30 kg dams deviate. Heritability estimates of survival rates during pre-weaning periods were not significantly different from zero, indicating that improvement by simple selection is probably limited.

Objective This study was performed to explore the relationship between various clinical factors and the prognosis of limb osteosarcoma. Methods We retrospectively analyzed the clinical data of 336 patients with limb osteosarcoma treated from June 2000 to August 2016 at 7 Chinese cancer centers. Data on the patients’ clinical condition, treatment method, complications, recurrences, metastasis, and prognosis were collected and analyzed. Kaplan–Meier analysis and Cox regression models were used to analyze the data. Results The patients comprised 204 males and 132 females ranging in age from 6 to 74 years (average, 21.1 years). The overall 3- and 5-year survival rates were 65.0% and 55.0%, respectively. The 5-year overall survival rate was 64.0% with standard chemotherapy and 45.6% with non-standard chemotherapy. Cox regression analysis demonstrated that standard chemotherapy, surgery, recurrence, and metastasis were independent factors associated with the prognosis of limb osteosarcoma. Conclusion The survival of patients with limb osteosarcoma can be significantly improved by combining standard chemotherapy and surgery. The overall survival rate can also be improved by adding methotrexate to doxorubicin–cisplatin–ifosfamide triple chemotherapy.

Introduction surgical treatment of elderly and senile cancer patients is becoming more common, due to the growing number of aging population. Optimization of surgical treatment of elderly patients remains an actual problem due to a significant number of comorbidities and a decrease in the functional reserves of the organism.Purpose of the study. Analysis of the survival and determination of risk factors affecting the life expectancy of elderly patients with II–III stages of colon cancer.Materials and methods. The analysis of case histories of 40 elderly and senile patients with II–III stages of the colon cancer, operated in the Zaporizhzhia Regional Clinical Oncology Dispensary in 2016.Results and discussion. When analyzing the survival rate, it was noted that the overall 2-year survival rate was 80%. The analysis of survival depending on the stage showed that the total 2-year survival in patients with II stage of disease was 91,3%, and among patients with III stage it was 64,7% (p < 0,05). The overall 2-year survival for men was 68,2%, while for women it was 94,4% (p < 0,05). In patients with tumor localization in the right half of the large intestine, overall survival rates were lower compared with patients with tumor localization in the left half (62,5% and 91,7%, respectively, p < 0.05). Indicators of total 2-year survival in patients with I, II, III degree of blood loss were respectively 94,4%, 83,3%, 50% (p < 0,05).The stage of the disease, tumor localization, sex, the degree of intraoperative blood loss, leukocytosis significantly correlate with the overall survival rates in elderly and senile patients with II–III stages of colon cancer(p < 0,05). Further study and search for new prognostic factors of surgical risk in elderly and senile patients with colorectal cancer are needed. Keywords: colon cancer, survival, operative treatment, lymphodissection, laparoscopy.

The frequency of smoking among patients with primary lung cancer diagnoses admitted to the Hospital de Clinicas de Porto Alegre (HCPA) during the 1980's was investigated. The objective of this study was to analyze cigarette consumption patterns through the number of cigarettes smoked per day and the age at which smoking began, correlating this data to the overall survival rate and histological type of the lung cancer. Methods: This retrospective study analyzed patients with primary lung cancer diagnosed at the HCPA between January 1980 and December 1989. All patients considered underwent follow-up for at least three years. Patient information was obtained either from the hospital's records or by contacting patients via letter or phone. Results: More than 90 percent of the patients were smokers or had smoked previously; most had started smoking before the age of 20.The overall 24-month survival rate after diagnosis varied depending on whether the patient had smoked less than 40 cigarettes per day or not. The percentage of smokers and non-smokers was established for each histological type, with the bronchoalveolar adenocarcinoma type showing the highest percentage of non-smokers (40 percent). Conclusion:The overall survival rates of patients with lung cancer was related to the number of cigarettes smoked, and not to the fact of the patient having smoked or not.The number of smokers among patients with lung cancer was not so high only for the bronchoalveolar adenocarcinoma histological type.

Objective To analyze the survival rate of a nonselected pyriform sinus cancer population. Study Design Case series with chart review. Setting University hospital. Subjects and Methods A total of 122 patients were included in this study covering the 2002-2008 period. All patients had squamous cell carcinoma originating from the pyriform sinus. Survival and prognostic factors were analyzed. Results The 3- and 5-year overall survival rates were 39.7% and 2.4%, respectively. The 3- and 5-year survival rates without recurrence were 34% and 27%, respectively. The median survival rates by UICC stage were as follows: stage 1 and 2 patients, 60 months; stage 3, 40 months; stage 4, 19 months. Stage 4 patients had a lower median survival rate than other stages ( P = .039). The 5-year survival rate was 46% for patients having T3-T4 operable cancers treated by surgery vs 45% for patients treated by laryngeal conservation protocol (not significant). The 5-year survival rate for patients having nonoperable T4 cancers was 17.2%. The 3- and 5-year overall survival rates of N0 patients was significantly higher than N1 patients ( P = .042). N2 and N3 patients had 100% 5-year mortality. Conclusion This study showed that overall survival and therapeutic management depend on the initial stage of pyriform sinus cancer, notably on the N status. In particular, nonoperable T4 pyriform sinus cancer and N2 and N3 patients had a very poor prognosis. A laryngeal conservation protocol seemed as effective as surgical management in terms of survival.

AbstractHepatic pedicle clamping reduces intraoperative blood loss and the need for transfusion, but its long-term effect on survival and recurrence remains controversial. The aim of this meta-analysis was to evaluate the effect of the Pringle maneuver (PM) on long-term oncological outcomes in patients with primary or metastatic liver malignancies who underwent liver resection. Literature was searched in the Cochrane Central Register of Controlled Trials (CENTRAL), Medline (via PubMed), and Web of Science databases. Survival was measured as the survival rate or as a continuous endpoint. Pooled estimates were represented as odds ratios (ORs) using the Mantel–Haenszel test with a random-effects model. The literature search retrieved 435 studies. One RCT and 18 NRS, including 7480 patients who underwent liver resection with the PM (4309 cases) or without the PM (3171 cases) were included. The PM did not decrease the 1-year overall survival rate (OR 0.86; 95% CI 0.67–1.09; P = 0.22) or the 3- and 5-year overall survival rates. The PM did not decrease the 1-year recurrence-free survival rate (OR 1.06; 95% CI 0.75–1.50; P = 0.75) or the 3- and 5-year recurrence-free survival rates. There is no evidence that the Pringle maneuver has a negative effect on recurrence-free or overall survival rates.

Summary. Preweaning lamb survival for intervals of up to 8 weeks was studied in the progeny of the local fat-tailed Naeemi and imported Border Leicester × Merino ewes mated to Naeemi rams. An intensive system of management with zero grazing was used to conform to the most probable type of production system to be used in Kuwait. The effects of year and season of lambing, litter size, sex, genetic group and birth weight were determined. Lamb survival rates from birth to 1 week, from 1 to 4 weeks and from 4 to 8 weeks were 96, 99 and 97% respectively. Overall survival from birth to weaning at 8 weeks was 91%. Genetic group, litter size, sex of lamb and year of lambing had no significant effects on survival. Season was significant from birth to 1 week, from 4 to 8 weeks and from birth to 8 weeks. Lamb birth weight was the most important factor affecting lamb survival, through a quadratic relationship between weight and survival.

Data on 7757 kid's records (2424 Alpine, 1417 Granadina, 2225 Nubian, 1043 Saanen and 648 Toggenburg) were used to study the effect of the breed, sex, litter size, birth weight, dam age, year of birth and birth period (October–January, February, March, April–July) on kid survival rates from 0–15, 16–90 and 91–210 days of age. Survival of kids was in general highest in Granadina and lowest in Toggenburg, while values in the other breeds, tended to be intermediate. Survival in males was lower than in female kids 0–15 and 16–90 d of age (P < 0.001). Kids weighing more than 3 kg at birth had higher survival than those weighing 2 kg or less (P < 0.01). Year and period of birth (P < 0.001) affected all survival rates, and kids born from October to January always showed a higher survival rate than those born from April to July. Breed with birth period, age of dam and birth weight interactions (P < 0.05) indicated a greater sensitivity of Alpines, Saanen and Toggenburg to the above factors. Key words: Goat kids, Alpine, Granadina, Nubian, Saanen, Toggenburg, survival

Abstract Background It remains controversial whether patients with Stage II colon cancer would benefit from chemotherapy after radical surgery. This study aims to assess the real effectiveness of chemotherapy in patients with stage II colon cancer undergoing radical surgery and to construct survival prediction models to predict the survival benefits of chemotherapy. Methods Data for stage II colon cancer patients with radical surgery were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (1:1) was performed according to receive or not receive chemotherapy. Competitive risk regression models were used to assess colon cancer cause-specific death (CSD) and non-colon cancer cause-specific death (NCSD). Survival prediction nomograms were constructed to predict overall survival (OS) and colon cancer cause-specific survival (CSS). The predictive abilities of the constructed models were evaluated by the concordance indexes (C-indexes) and calibration curves. Results A total of 25,110 patients were identified, 21.7% received chemotherapy, and 78.3% were without chemotherapy. A total of 10,916 patients were extracted after propensity score matching. The estimated 3-year overall survival rates of chemotherapy were 0.7% higher than non- chemotherapy. The estimated 5-year and 10-year overall survival rates of non-chemotherapy were 1.3 and 2.1% higher than chemotherapy, respectively. Survival prediction models showed good discrimination (the C-indexes between 0.582 and 0.757) and excellent calibration. Conclusions Chemotherapy improves the short-term (43 months) survival benefit of stage II colon cancer patients who received radical surgery. Survival prediction models can be used to predict OS and CSS of patients receiving chemotherapy as well as OS and CSS of patients not receiving chemotherapy and to make individualized treatment recommendations for stage II colon cancer patients who received radical surgery.
