Mental health outcomes in elderly men with prostate cancer

ObjectiveTo examine the burden of mental health issues (MHI), namely anxiety, depressive disorders, and suicide, in a population-based cohort of older men with localized prostate cancer and to evaluate associations with primary treatment modality.Patients and methodsA total of 50,856 men, who were 65 years of age or older with clinically localized prostate cancer diagnosed between 1992 and 2005 and without a diagnosis of mental illness at baseline, were abstracted from the Surveillance, Epidemiology, and End Results–Medicare database. The primary outcome of interest was the development of MHI (anxiety, major depressive disorder, depressive disorder not elsewhere classified, neurotic depression, adjustment disorder with depressed mood, and suicide) after the diagnosis of prostate cancer.ResultsA total of 10,389 men (20.4%) developed MHI during the study period. Independent risk factors for MHI included age≥75 years (hazard ratio [HR] = 1.29); higher comorbidity (Charlson comorbidity index≥3, HR = 1.63); rural hospital location (HR = 1.14); being single, divorced, or widowed (HR = 1.12); later year of diagnosis (HR = 1.05); and urinary incontinence (HR = 1.47). Black race (HR = 0.79), very high-income status (HR = 0.87), and definitive treatment (radical prostatectomy [RP], HR = 0.79; radiotherapy [RT], HR= 0.85, all P<0.001) predicted a lower risk of MHI. The rates of MHI at 10 years were 29.7%, 29.0%, and 22.6% in men undergoing watchful waiting (WW), RT, and RP, respectively.ConclusionOlder men with localized prostate cancer had a significant burden of MHI. Men treated with RP or RT were at a lower risk of developing MHI, compared with those undergoing WW, with median time to development of MHI being significantly greater in those undergoing RP compared with those undergoing RT or WW.     

Human evolution and tears of the rotator cuff

Purpose

Humans differ from other great ape species in their propensity to develop tears of the rotator cuff. The aim of this study was to compare the anatomical risk factors for subacromial impingement and rotator cuff tears amongst the great apes and to determine which features may be accentuated in humans and therefore play a more significant role in disease aetiology.

Methods

Orthogonal digital photographs of 22 human, 17 gorilla, 13 chimpanzee and 12 orangutan dry bone scapula specimens oriented in the glenoid plane were taken. Anatomical measurements were preformed using a calibrated digital image technique and the results scaled according to scapula vertebral border length.

Results

Of the ten anatomical features associated with subacromial impingement and rotator cuff tears in humans, none were shown to be accentuated and significantly different to the other species studied. However the human supraspinatus fossa was shown to be significantly smaller.

Conclusions

These results indicate that an alternative primary aetiological factor for rotator cuff tears must exist. A reduction in the size of the supraspinatus fossa in human scapulae suggests that structural insufficiency of the supraspinatus or a change in rotator cuff force vectors could play a role.     

Single-Institution Retrospective Comparison of Preoperative Versus Definitive Chemoradiotherapy for Adenocarcinoma of the Esophagus

Purpose

We sought to determine the impact of esophagectomy on survival in patients with adenocarcinoma of the esophagus cancer after chemoradiotherapy (CRT).

Methods

A database of esophageal cancer was queried for nonmetastatic patients with adenocarcinoma treated between 2000 and 2011 with CRT. Overall survival (OS) and recurrence-free survival (RFS) curves were calculated according to the Kaplan–Meier method and log-rank analysis. Multivariate analysis was performed by the Cox proportional hazard model.

Results

We identified 154 patients (60 without surgery; 94 with surgery) who were included in the analysis. The only differences between the 2 groups were more advanced disease stage, improved performance status, and younger age in the surgery group. Patients undergoing surgery had significantly higher survival. Median and 5-year OS for surgical patients were 4.1 years and 43.6 %, versus 1.9 years and 35.6 % for nonsurgical patients (p = 0.007). Multivariate analysis for OS and RFS revealed that factors associated with increased survival were surgical resection, tumor length < 5 cm, male gender, and lower stage. Age, tumor location, radiation dose/technique, and induction chemotherapy were not prognostic. There was a trend toward improved survival on univariate analysis (p = 0.10) and multivariate analysis (p = 0.063) for surgical patients compared to nonsurgical patients who were healthy enough for surgery before CRT (n = 38), and no difference in OS in nonsurgical patients healthy enough for surgery after CRT (n = 22).

Conclusion

Esophagectomy after CRT is associated with improved survival in patients with adenocarcinoma after CRT. Trimodal therapy should continue to remain the standard of care for esophageal adenocarcinoma.

Use of percutaneous drainage to treat hepatic abscess after radiofrequency ablation of metastatic pancreatic adenocarcinoma

Radiofrequency ablation (RFA) is well described in the treatment of primary hepatic malignancies and colorectal carcinoma hepatic metastases. A known complication of RFA is the development of hepatic abscess. The management of hepatic abscesses subsequent to RFA for metastatic disease is not well described. A 49-year-old female with pancreatic adenocarcinoma underwent pancreaticoduodenectomy followed by adjuvant chemoradiation. Following 6 months' treatment, a new liver metastasis was identified. It remained stable for 6 months during additional chemotherapy and thereafter was treated with RFA. Three weeks after RFA, the patient presented with malaise and leukocytosis, and a CT scan demonstrated a large hepatic abscess at the site of the RFA. She remained febrile despite needle aspiration and intravenous antibiotics. A percutaneous drain was placed and the symptoms resolved. Contrast injection of the drain 4 weeks later demonstrated resolution of the abscess cavity but communication with the biliary tree. The drain was removed and the tract embolized with Gel-foam to prevent complications of biliary-cutaneous fistula. She remains well without evidence of abscess or disease recurrence. Thus, RFA can be used in treatment of limited isolated hepatic metastases from previously treated pancreatic adenocarcinoma. However, the incidence of hepatic abscess is increased due to bilioenteric anastomosis; extended antibiotic prophylaxis should be considered.     

Isolated mediastinal lymphangioma herniating through the intercostal space

Lymphangiomas are congenital malformations of the lymphatic system, and 90% have manifested by the end of the second year of life. While 75% of these are located in the cervical region, only 2% to 3% are associated with an intrathoracic extension. An isolated mediastinal lymphangioma without a cervical component is an uncommon occurrence. Presented here is an isolated mediastinal lymphangioma that herniated through the intercostal space to present as a cystic mass in the parasternal region, which has not been reported so far.     

Rapid Progression of Native Renal Artery Fibromuscular Dysplasia Following Kidney Donation

Fibromuscular dysplasia is the second commonest anatomical abnormality apart from multiple renal arteries in the potential live donors. Pretransplant evaluation of the donors may include an angiography to evaluate the renal arteries, and failure to recognize renal arterial stenosis, particularly fibromuscular dysplasia, by noninvasive methods may eventually lead to hypertension and ischemic renal failure. We report a case of fibromuscular dysplasia that was undetected by computed tomographic angiography prior to donation. One year after kidney donation, it rapidly progressed to severe symptomatic stenosis with hypertension and acute renal failure. Following renal artery angioplasty, her blood pressure normalized over a period of 2 weeks without any need for antihypertensive medications and the serum creatinine returned to her baseline. The acceptability of renal donors with fibromuscular dysplasia depends on the age, race and the availability of the other suitable donors. Mild fibromuscular dysplasia in a normotensive potential renal donor cannot be considered a benign condition. Such donors need regular follow-up postdonation for timely detection and treatment.     

Laparoscopic Colorectal Surgery for Obese Patients: Decreased Conversions with the Hand-Assisted Technique

Background

Laparoscopic surgery benefits obese patients but technical difficulties associated with suboptimal exposure and access in these subjects may prompt conversion to open surgery. Hand-assisted laparoscopic surgery (HALS) confers advantages over standard laparoscopy (LAP) by facilitating tactile feedback, assisted dissection, and retraction. These benefits could be particularly valuable in obese patients, allowing completion of difficult laparoscopic procedures in this subgroup. Our aim was to compare intra-operative and post-operative outcomes of HALS and LAP approaches in obese patients undergoing colorectal resection at our institution.

Methods

A retrospective study of a prospectively maintained laparoscopic colorectal surgery database was performed. HALS and LAP cases performed in obese patients (body mass index (BMI)?>30) were identified and compared for the following outcomes: operative time, intra-operative complications, rate of conversion to open, blood loss, length of stay, post-operative morbidity, and mortality. Outcomes for the converted patients were included on an intention-to-treat basis for all primary analyses. A secondary analysis of nonconverted and converted cases was also performed.

Results

Over a 5-year period, 496 obese patients underwent laparoscopic colorectal resection; 86 HALS and 410 LAP cases. The two groups were comparable in terms of age, gender, BMI, and indications for surgery. Conversion to open surgery was less often necessary in HALS compared to LAP cases (3.5 % vs. 12.7 %, p?=?0.014). The LAP group had a significantly smaller incision length for specimen extraction (HALS (7.0?±?1.3 cm) vs. LAP (5.7?±?2.1 cm), p?<?0.001). Length of stay, operative time, morbidity, and mortality rates were comparable between the two groups.

Conclusion

In obese patients who require colectomy, the HALS approach increases the likelihood of a successful minimally invasive operation. At the cost of a clinically negligible increase in incision length, HALS may save a high-risk group conversion to formal laparotomy and the adverse outcomes related to this.
