Perioperative outcomes and long-term quality of life after total pancreatectomy.

BACKGROUND: Total pancreatectomy is required to treat diseases involving the entire pancreas, and is characterized by high morbidity rates and impaired long-term quality of life (QoL). To date, risk factors associated with perioperative and long-term outcomes have not been determined fully. METHODS: Data from patients undergoing total pancreatectomy between 2000 and 2014 at two high-volume centres were analysed retrospectively to assess risk factors for major surgical complications. Short Form (SF) 36, European Organisation for Research and Treatment of Cancer QLQ-PAN26 and Audit of Diabetes Dependent questionnaires, as well as an original survey were used to investigate factors influencing QoL. RESULTS: A total of 329 consecutive patients underwent total pancreatectomy in the two centres. Overall, total pancreatectomy was associated with a morbidity rate of 59·3 per cent and a 30-day mortality rate of 2·1 per cent. Age over 65 years and long duration of surgery (more than 420 min) were independently associated with major complications (at least Clavien-Dindo grade III). QoL analysis was available for 94 patients (28·6 per cent) with a median follow-up of 63 (i.q.r. 20-109) months; the most common indication for total pancreatectomy in these patients was intraductal papillary mucinous neoplasms (46 per cent). Both physical (PCS) and mental (MCS) component summary scores of SF-36® were lower after total pancreatectomy compared with scores for a normative population (P = 0·020 and P < 0·001 respectively). Linear regression analysis showed that young age, abdominal pain and worse perception of body image were negatively associated with the PCS, whereas diabetes, sexual satisfaction and perception of body image affected MCS. CONCLUSION: Total pancreatectomy can be performed with acceptable morbidity and mortality rates. Older patients had a higher risk of postoperative complications but reported better QoL than younger patients.

ANTECEDENTES: La pancreatectomía total es una cirugía necesaria para tratar enfermedades que afectan a la totalidad el páncreas y se caracteriza por una alta morbilidad y una disminución de la calidad de vida (QoL) a largo plazo. Hasta la fecha, los factores de riesgo asociados a los resultados perioperatorios y a largo plazo no han sido completamente determinados. MÉTODOS: Los datos de los pacientes que se sometieron a una pancreatectomía total desde el año 2000 al 2015 en dos centros de alto volumen se analizaron retrospectivamente para evaluar los factores de riesgo de las complicaciones quirúrgicas mayores. Se utilizaron el SF-36, el EORTC-PAN-26, los cuestionarios ADD-QoL y una encuesta original para investigar los factores que afectan la QoL. RESULTADOS: Un total de 329 pacientes consecutivos se sometieron a una pancreatectomía total en los dos centros. En general, la pancreatectomía total se asoció a un 59,3% de morbilidad y un 2,1% de mortalidad a los 30 días. La edad > 65 años y el tiempo operatorio prolongado (> 420 minutos) se asociaron de forma independiente a las complicaciones Clavien-Dindo ≥ III. El análisis de QoL estuvo disponible en 94 (28,6%) de los pacientes con una mediana de seguimiento de 63 meses (rango intercuartílico 20-109) y la indicación más común fue una neoplasia papilar mucinosa intraductal (IPMN) (45,7%). Las puntuaciones del SF-36 fueron más bajas en ambos componentes sumatorios físico (PCS) y mental (MCS) (P = 0,002; P < 0,001) en comparación con una población normal. El modelo de regresión lineal mostró que la edad joven, el dolor abdominal y la peor percepción de la imagen corporal se asociaron negativamente con el PCS; mientras que la diabetes, la satisfacción sexual y la percepción de la imagen corporal afectaron al MCS. CONCLUSIÓN: Se puede realizar una pancreatectomía total con morbilidad y mortalidad aceptables. Los pacientes de mayor edad tienen un riesgo más elevado de complicaciones postoperatorias, pero presentaron mejor QoL que los pacientes más jóvenes.

Genetic And Morphological Evaluation (GAME) score for patients with colorectal liver metastases.

BACKGROUND: This study sought to develop a clinical risk score for resectable colorectal liver metastasis (CRLM) by combining clinicopathological and clinically available biological indicators, including KRAS. METHODS: A cohort of patients who underwent resection for CRLM at the Johns Hopkins Hospital (JHH) was analysed to identify independent predictors of overall survival (OS) that can be assessed before operation; these factors were combined into the Genetic And Morphological Evaluation (GAME) score. The score was compared with the current standard (Fong score) and validated in an external cohort of patients from the Memorial Sloan Kettering Cancer Center (MSKCC). RESULTS: Six preoperative predictors of worse OS were identified on multivariable Cox regression analysis in the JHH cohort (502 patients). The GAME score was calculated by allocating points to each patient according to the presence of these predictive factors: KRAS-mutated tumours (1 point); carcinoembryonic antigen level 20 ng/ml or more (1 point), primary tumour lymph node metastasis (1 point); Tumour Burden Score between 3 and 8 (1 point) or 9 and over (2 points); and extrahepatic disease (2 points). The high-risk group in the JHH cohort (GAME score at least 4 points) had a 5-year OS rate of 11 per cent, compared with 73·4 per cent for those in the low-risk group (score 0-1 point). Importantly, in cohorts from both the JHH and MSKCC (747 patients), the discriminatory capacity of the GAME score was superior to that of the Fong score, as demonstrated by the C-index and the Akaike information criterion. CONCLUSION: The GAME score is a preoperative prognostic tool that can be used to inform treatment selection.

Motivational interviewing-based training vs traditional training on the uptake of cervical screening: a quasi-experimental study.

OBJECTIVES: Cervical cancer, a major health issue affecting women, is preventable and can be successfully treated. It is essential that measures are taken to improve the uptake of screening for this cancer. The aim of this study was to compare the effects of motivational interviewing (MI)-based training and traditional training on the frequency of cervical cancer screening tests in a group of working female teachers. STUDY DESIGN: This is a quasi-experimental study. METHODS: This research was conducted in 2017 among 134 teachers (aged 30-60 years) working in southeastern Iran. The participants were selected from among the eligible individuals and subsequently divided into MI-based training and traditional training groups (n = 67 for each group). Each group received a three-session training program, and 20 weeks after the end of the last training session, the information obtained from cervical cancer screening tests was documented. To analyze the data, independent t-test and Chi-squared test were run in SPSS, version 21. RESULTS: There was no significant difference between the two groups in terms of demographic characteristics such as age, age at the first pregnancy, age of marriage, the number of parities, and educational level. Twenty weeks after intervention, 20.9% of the MI-based training group underwent Pap smear screening test, while 9% of the women in the traditional training group took the test, indicating a statistically significant difference between the two groups (P < 0.0.5). CONCLUSION: MI-based training has a significant positive effect on women's compliance with cervical cancer screening tests. Therefore, it is recommended that this technique be adopted in women's health centers. TRIAL REGISTRATION NUMBER: IRCT2017100729954N4.

Validation of histomolecular classification utilizing histological subtype, MUC1, and CDX2 for prognostication of resected ampullary adenocarcinoma.

BACKGROUND: Outcomes for ampullary adenocarcinomas are heterogeneous, and numerous methods of categorisation exist. A histomolecular phenotype based on histology, caudal-type homeodomain transcription factor 2 (CDX2) staining and Mucin 1 (MUC1) staining has recently been tested and validated in two cohorts. We attempt to validate this classification in a large patient population. METHODS: Tissue samples from 163 patients with resected ampullary adenocarcinoma were classified based on histology and immunohistochemical expression of CDX2 and MUC1. A pancreaticobiliary histomolecular classification (PB) was defined as a sample with pancreaticobiliary histology, positive MUC1 and negative CDX2 expression. RESULTS: There were 82 deaths; median follow-up of 32.4 months; and median overall survival of 87.7 (95% CI 42.9-109.5) months. PB comprised 28.2% of the cases. Factors associated with overall survival were histological subtype (P=0.0340); T1/2 vs T3/4 (P=0.001); perineural (P<0.0001) and lymphovascular (P=0.0203) invasion; and histomolecular intestinal histomolecular phenotype (INT) vs PB phenotype (106.4 vs 21.2 months, P<0.0001). Neither MUC1 nor CDX2 was statistically significant, although MUC1 positivity defined as ⩾10% staining was significant (P=0.0023). In multivariate analysis, age (HR 1.03), PB phenotype (HR 2.26) and perineural invasion (PNI; HR 2.26) were associated with poor survival. CONCLUSIONS: The prognostic ability of histomolecular phenotype has been validated in an independent cohort of ampullary adenocarcinoma patients.

Synthesis and antinociceptive behaviors of new methyl and hydroxyl derivatives of phencyclidine.

Phencyclidine (I) and its derivatives show such pharmacological behaviors as analgesic, anticonsulvant, anti-anxiety and antidepressant, while interacting with central nervous system. In this study, new methyl and hydroxyl derivatives of PCP were synthesized and their antinociceptive behaviors in animals were examined by measuring the number of writhing in a writhing test of visceral pain and the pain scores in Formalin test. Compared to control and PCP groups, findings in experimental groups indicated the new synthesized analogues (compounds II, III and V, 10 mg/kg) of PCP were able to produce more analgesic effects in formalin and writhing tests, especially for compound V. It was concluded that the new synthesized derivatives of PCP could substantially and respectively diminish acute and chronic pains.
