The impact of frontal and non-frontal brain tumor lesions on Wisconsin Card Sorting Test performance

Several lesion and imaging studies have suggested that the Wisconsin Card Sorting Test (WCST) is a measure of executive dysfunction. However, some studies have reported that this measure has poor anatomical specificity because patients with either frontal or non-frontal focal lesions exhibit similar performance. This study examined 25 frontal, 20 non-frontal low-grade brain tumor patients, and 63 normal controls (NC) on the WCST. The frontal patients were also assigned to either a left frontal (n=10) group or a right frontal group (n=15) and compared with the non-frontal group and NC. It was hypothesized that the frontal brain tumor patients would display greater deficits on categories achieved and a higher number of perseverative errors than non-frontal brain tumor patients on the WCST. Finally, it was predicted that right frontal brain tumors would result in greater executive functioning deficits than left frontal or non-frontal brain tumors. Results indicated that the left frontal group achieved the fewest categories and committed the most perseverative errors compared to the other patient and normal control groups. In addition, the left frontal group committed significantly more perseverative errors than the right frontal group. These results suggest that the WCST is sensitive to the effects of low-grade brain tumors on executive functioning.

Survival rate comparisons amongst cervical cancer patients treated with an open, robotic-assisted or laparoscopic radical hysterectomy: A five year experience.

BACKGROUND The purpose of this retrospective study was to assess the 5-year survival outcomes of cervical cancer patients who underwent an, open radical hysterectomy (ORH), robotic-assisted radical hysterectomy (RRH) or laparoscopic radical hysterectomy (LRH) for the treatment of their disease. METHOD We conducted a review of all cervical cancer patients who were managed with an ORH, RRH or LRH. RESULT Forty-nine patients were treated with LRH, 58 were managed via RRH and 39 patients underwent an ORH. The LRH (1.78 h) patients had a significantly shorter operative duration than the RRH (2.88 h) and ORH (2.39 h) subjects (p < 0.001). Blood loss was the highest in the ORH (475 cc) group (RRH = 207 cc and LRH = 312 cc) (P < 0.001). Moreover, the ORH (5.04 days) patients had a significantly longer hospital stay than the LRH (2.95 days) and RRH (2.50 day) subjects (P < 0.001). Kaplan-Meier survival analysis revealed a progression free survival (PFS) rate of 84.6% for the ORH group, 89.8% for the LRH group and 89.7% for the RRH patients (P = 0.271) at 60 months; overall survival was 92.3% for the ORH group, 95.9% for the LRH group and 96.6% for the RRH patients (P = 0.80). CONCLUSION The results from this study suggest that, irrespective of operative approach, patients who underwent a radical hysterectomy for early stage cervical cancer attained similar 5-year disease free and overall survival outcomes.

Contemporary diagnosis and management of a uterine arteriovenous malformation.

BACKGROUND: Uterine arteriovenous malformations (AVMs) are extremely rare and can result in severe complications. Experience with diagnosis and management of these vascular malformations is very limited. CASE: We report on a patient with a history of nonmetastatic gestational trophoblastic disease. The patient developed a concomitant 4.4-cm intrauterine mass, suggestive of a molar pregnancy, during her second pregnancy. Despite suction and sharp curettage, the mass and menorrhagia persisted. After complex diagnostic imaging, the diagnosis of a uterine AVM was made. Subsequently, the patient underwent uterine arterial embolization and laparoscopic surgery to resect the mass. CONCLUSION: Because uterine AVMs are infrequently encountered, they initially may not be included in the differential diagnosis. The use of contemporary imaging, interventional radiology, and surgery can optimize patient outcome.

A comparison of open surgery, robotic-assisted surgery and conventional laparoscopic surgery in the treatment of morbidly obese endometrial cancer patients.

Background and Objectives: The intent of this retrospective study was to assess the operative outcomes of morbidly obese endometrial cancer patients who were treated with either open surgery (OS) or a minimally invasive procedure. Methods: Morbidly obese (body mass index [BMI] > 40 kg/m2) patients with endometrial cancer who underwent OS, robotic-assisted laparoscopic surgery (RS), or conventional laparoscopic surgery (LS) were eligible. We sought to discern any outcome differences with regard to operative time, perioperative complications, and hospital stay. Results: Sixteen patients were treated with LS (BMI = 47.9 kg/m2), 13 were managed via RS (BMI = 51.2 kg/m2), and 24 underwent OS (BMI = 53.7 kg/m2). The OS (1.35 hours) patients had a significantly shorter operative duration than the LS (1.82 hours) and RS (2.78 hours) patients (P < .001); blood loss was greater in the OS (250 mL) group in comparison with the RS (100 mL) and LS (175 mL) patients (P = .002). Moreover, the OS (4 days) subjects had a significantly longer hospital stay than the LS (2 days) and RS (2 days) patients (P = .002). Conclusion: In the present study, we ascertained that minimally invasive surgery was associated with longer operative times but lower rates of blood loss and shorter hospital stay duration compared with treatment comprising an open procedure.

Clinical Predictors of Depression in Patients with Low-Grade Brain Tumors: Consideration of a Neurologic Versus a Psychogenic Model

Few studies have examined quality of life issues in patients with brain tumors, though coping with cancer is stressful and is associated with heightened levels of depression. We used regression to examine the clinical factors that might predict depression in a group of 57 adults with low-grade brain tumors after surgery but prior to radiotherapy and chemotherapy. A neurological model comprised of tumor characteristics and treatment was compared with a psychogenic model comprised of both psychosocial and psychodynamic variables. Demographic variables and level of fatigue were also included. A model consisting primarily of fatigue (also clinically elevated) and secondarily of tumor location and aggressiveness of surgical treatment accounted for 33% of the depression score. In a small group at a later follow-up when patient depression was clinically elevated (4–6 years after baseline), fatigue, female sex, cognitive dysfunction, increased family support, and increased report of physical symptoms were associated with depression. The late out findings remain exploratory because of the small sample size, but they suggest that depression develops over time and results from a combination of neurological and psychosocial problems that ensue initial treatments. Treating these collateral problems may reduce the complications from depression.

The safety and feasibility of robotic-assisted lymph node staging in early-stage ovarian cancer.

Objectives The purpose of this study was to report on the safety and feasibility of robotic-assisted systematic lymph node staging in the management of early-stage ovarian cancer. Methods We retrospectively reviewed the charts of presumed early-stage (International Federation of Gynecology and Obstetrics (FIGO) stages I and II) ovarian cancer patients who underwent robotic-assisted surgery that incorporated a systematic pelvic and para-aortic lymphadenectomy from January 2009 until December 2013. Patient demographics, operative characteristics, pathology, lymph node counts, surgical complications, and hospital stay were evaluated. Results A total of 26 early-stage ovarian cancer patients were identified. The mean operating time was 2.90 hours, and the estimated blood loss was 63 mL; there were no intraoperative complications although 1 patient’s surgery was significantly prolonged due to pelvic adhesions. The mean number of pelvic and para-aortic lymph nodes removed was 14.6 (2.3% incidence of pelvic lymph node metastases) and 5.8 (3.3% incidence of para-aortic lymph node metastases), respectively. The patients’ mean duration of hospital stay was 18.4 hours, and 2 patients were readmitted for either a postoperative wound infection or vaginal dehiscence. Conclusions The results from this study suggest that robotic-assisted surgical staging in the management of presumed early-stage ovarian cancer is both feasible and associated with a minimal patient complication rate. We encountered a low incidence of lymph node metastases, and the readmission rate was favorable. Nevertheless, because the prevalence of lymph node metastases can approach 20% in select patients, physicians should consider a systematic lymph node resection to confer an optimal clinical assessment.

Same-Day Discharge in Clinical Stage I Endometrial Cancer Patients Treated with Total Laparoscopic Hysterectomy, Bilateral Salpingo-Oophorectomy and Bilateral Pelvic Lymphadenectomy

Objectives: The purpose of this retrospective study was to evaluate the capacity for same-day discharge in clinical stage I endometrial cancer (EC) patients treated with total laparoscopic hysterectomy (TLH), bilateral salpingo-oophorectomy (BSO) and bilateral pelvic lymph node dissection (BPLND). Methods: We retrospectively reviewed the charts of stage I EC patients who were treated with TLH, BSO and BPLND and discharged on the same day. The intra- and postoperative clinical variables (e.g., age, complications, surgery time, patient hospital stay) were evaluated in an attempt to discern which factors may predispose a patient to same-day discharge. Results: Twenty-one patients were successfully discharged on the same day of surgery. Mean operative time was 1.48 h and length of hospital stay was 6.35 h. There were no intraoperative complications or hospital readmissions. Conclusions: We present a single, institutional experience solely assessing the capacity for same-day discharge in clinical stage I EC patients treated with TLH, BSO and BPLND. Since the postoperative complication rate was minimal with no hospital readmissions, we suggest that particularly selected stage I EC patients are amenable to outpatient management.

Perivascular Epithelioid Cell Neoplasms: A Systematic Review of Prognostic Factors

Perivascular epithelioid cell tumors (PEComas) are rare, soft tissue tumors characterized by epithelioid cells with clear or eosinophilic cytoplasm and a perivascular disbursement. We compiled the treatment and follow-up results from an extensive collection of reported gynecologic PEComa cases and statistically analyzed their respective therapy modalities and corresponding patient outcomes. In the group of patients with PEComa who received surgical management alone, there was a tendency for them to exhibit a lower disease recurrence rate. Conversely, patients with PEComa who initially received surgery and chemotherapy or radiation therapy were associated with a higher disease recurrence rate (P =.024). Metastatic involvement was related to higher patient mortality rates (P =.0001), although this finding was unrelated to treatment type. Surgical management alone may suffice for nonaggressive lesions, but chemotherapy and radiotherapy appear necessary for patients who present with high-risk histologic condition or metastatic disease. Because PEComas exhibit varying biologic behavior and an ill-defined presentation, the treatment for these lesions necessitates further evaluation.

Individual physician experience with laparoscopic supracervical hysterectomy in a single outpatient setting.

The authors report the surgical experience of a single physician operating at 1 outpatient surgery center using laparoscopic supracervical hysterectomy for the treatment of 100 patients with benign gynecologic disease. Operative status was evaluated in terms of patient morbidity, length of surgery, blood loss, and duration of hospital stay. The mean operative time was 2.6 hours, and the mean anesthesia time was 3.2 hours. The mean estimated blood loss was 116.6 mL, and the mean patient hospital stay was 16.5 hours. There were no reported intraoperative or postoperative complications. Laparoscopic supracervical hysterectomy was not feasible and was converted to laparotomy and total abdominal hysterectomy in 4 patients. The authors present one of the first individual physician experiences at a single outpatient surgery center using laparoscopic supracervical hysterectomy for benign gynecologic conditions. Optimal patient postoperative stay and a minimal complication rate suggest that this procedure performed at a single outpatient surgery center is feasible.

Attention in adult intracranial tumors patients.

This study investigated the neuropsychological effects of intracranial tumors on attention, prior to irradiation and chemotherapy. Subjects (n =55) being treated for low-grade, supratentorial brain tumors were administered tests of attention and working memory. We divided the tumor patients into a “superficial” regional group (e.g., gliomas that infiltrate white matter and meningiomas attached to the cortical surface) and classified them into four brain regions: anterior left side, anterior right side, posterior left side, posterior right side. The groups were also classified into either a combined anterior group or combined posterior group, and either a combined left hemispheric group or combined right hemispheric group. All groups were compared to deep tumor (DT) patients (e.g., pituitary and pineal tumors) and a demographically normal control (NC) group (n =63). While the NC group primarily outperformed the brain tumor groups on the neuropsychological measures, there were instances where the individual brain tumor groups demonstrated higher scores than the NC group. Significant differences among the brain tumor groups were only found on Digits Forward. The DT group performed significantly worse than the superficial regional groups and the combined anterior and combined posterior groups on Digits Forward. The DT group was also worse than the combined left hemispheric and right hemispheric groups on Digits Forward. The fact that the DT group performed similarly to the other patient groups on the remaining attention measures suggests that these tumors are associated with especially poor attentional performance.
