Epithelial ovarian tumors of borderline malignancy

Between January 1975 and January 1987, 80 patients underwent primary surgery at Brigham and Womens Hospital for epithelial ovarian tumors of borderline malignancy. Surgical staging revealed 52 (65%) patients with stage IA, 2 (2.5%) with stage IB, 10 (12.5%) with stage IC, 4 (5%) with stage II, 11 (13.8%) with stage III, and 1 (1.2%) with stage IV. All 37 patients with mucinous tumors had stage I disease, whereas 13 (33%) of 39 patients with serous tumors had stage II-IV disease. The mean sizes of mucinous and serous ovarian tumors were 18.7 and 10 cm, respectively. At initial surgery, 48 (60%) patients had a total abdominal hysterectomy with bilateral salpingo-oophorectomy and 16 (20%) had an oophorectomy. Sixteen (20%) patients underwent cystectomy, 6 (37.5%) of whom subsequently had an oophorectomy. All 10 patients treated by cystectomy alone have remained disease free. CA-125 levels were normal in 5 patients with stage I disease, but were elevated in 6 of 8 patients with more advanced tumors. Current disease status was determined in 72 patients (90%); 69 (95.8%) are alive and disease free, 1 (1.4%) patient is alive with tumor, and 2 (2.8%) patients died, free of disease.

The North American Menopause Society recommendations for clinical care of midlife women

In celebration of the 25th anniversary of The North American Menopause Society (NAMS), the Society has compiled a set of key points and clinical recommendations for the care of midlife women. NAMS has always been a premier source of information about menopause for both healthcare providers and midli

The Use of p16 in enhancing the histologic classification of uterine smooth muscle tumors.

Background Uterine smooth muscle tumors can usually be divided histologically into leiomyoma (L) and leiomyosarcoma (LMS). Occasionally, the histologic features are indeterminate and classified as smooth muscle tumor of uncertain malignant potential (STUMP). Recent gene expression studies have found p16 overexpressed in LMS when compared with normal myometrium. This study evaluated the protein expression of p16 by immunohistochemistry in LMS, L, and normal myometrium. Additionally, 8 tumors originally classified as STUMP were evaluated for p16 expression and correlated to their clinical outcome. Methods A tissue microarray was constructed and composed of 15 LMS, 8 STUMPs, 22 L, and 10 samples of normal myometrium. p16 expression was correlated with clinical outcome and histologic features. Results Twelve of the 15 LMS strongly and diffusely expressed p16, 3 of the L had focal p16 staining, and none of the normal myometria were p16 positive. Three of the tumors originally classified as STUMP developed metastatic disease and 2 of these tumors had strong, diffuse p16 positivity. Histologically, these 2 cases were characterized by coagulative tumor cell necrosis and only mild cytologic atypia. Conclusions p16 is preferentially expressed in LMS with only rare L showing positivity. Histologically, tumors with coagulative tumor cell necrosis alone were clinically LMS. In those cases in which the type of necrosis is uncertain (coagulative tumor cell vs. hyalinized), the addition of p16 may aid in discerning a subset of STUMP that should be classified as LMS.

Persistent gestational trophoblastic tumor after partial hydatidiform mole

The current study investigates the clinical characteristics of patients with partial molar pregnancy who developed persistent gestational trophoblastic tumor (GTT). Between January 1979 and January 1989, 16 of 240 (6.6%) patients, who were followed for partial mole, developed persistent GTT. Fifteen (94%) patients were diagnosed as having a missed abortion before evacuation and only 1 patient presented with excessive uterine size and theca lutein ovarian cysts and was felt to have molar disease. No patient presented with toxemia, hyperemesis, or hyperthyroidism. All 16 patients developed nonmetastatic GTT. Fifteen patients achieved complete remission with methotrexate-citrovorum factor and only 1 patient required combination chemotherapy to attain remission. None of the patients had histologic evidence of choriocarcinoma. Patients with partial mole who developed persistent GTT did not have clinical or pathological characteristics that distinguished them from other patients with partial mole. All patients with partial mole should be followed with measurement of hCG levels to assure gonadotropin remission.

Minimizing the risk of neurologic injury in gynecologic surgery.

OBJECTIVE: The association of intraoperative neurologic injuries with gynecologic surgical procedures is well established. The sequelae of such injuries are usually transient and resolve with minimal intervention, although long-term disability can and does occasionally occur. The purpose of this study was to examine the mechanisms by which these injuries occur in order to reduce the risk of their occurrence. DATA SOURCES: A MEDLINE search was performed cross-referencing the index terms “neurological injury” and “gynecological surgery,” from January 1, 1960 to December 31, 2002. METHODS OF STUDY SELECTION: This article, based on the data and results (Level I–III) obtained from the MEDLINE search, examined the most common neurologic injuries that occur in association with abdominal and vaginal surgical procedures routinely performed by gynecologists. TABULATION, INTEGRATION, AND RESULTS: Neurologic injuries after pelvic surgery all generally share a common etiology, specifically injury to one or more components of the lumbosacral nerve plexus. Three major factors that predispose to neurologic injury at the time of gynecological surgery are 1) the improper placement or positioning of self-retaining or fixed retractors, particularly those with deep lateral retractor blades; 2) improper positioning of patients in lithotomy position preoperatively; and 3) radical surgical dissection resulting in autonomic nerve disruption. Level I data strongly implicate the improper placement of self-retaining or fixed retractors as the most common cause of femoral nerve injury arising in association with abdominal surgical procedures. CONCLUSION: A thorough understanding of the anatomy of the lumbosacral nerve plexus and the mechanisms by which operative injuries to this plexus occur will enable the gynecologic surgeon to reduce the subsequent risk of their occurrence in his or her own surgical practice.

Atypical glandular cells of undetermined significance: A five-year retrospective histopathologic study

OBJECTIVE Our purpose was to ascertain the types and frequency of pathologic conditions associated with atypical glandular cells of undetermined significance on Papanicolaou smears. STUDY DESIGN A 5-year retrospective review of screening cervical cytologic examinations diagnosed as atypical glandular cells of undetermined significance was performed at the University of Virginia to determine pathologic findings associated with atypical glandular cells of undetermined significance on Papanicolaou smears stratified by subtype and overall. RESULTS Pathologic findings for the respective Papanicolaou smears with the diagnosis of atypical glandular cells of undetermined significance not otherwise specified, favor benign, squamous intraepithelial lesions, and favor neoplasia through the follow-up interval were as follows: squamous intraepithelial lesions in 11%, 8%, 38%, and 20%; adenocarcinoma in situ in 3%, 0%, 0%, and 10%; endometrial hyperplasia in 3%, 5%, 1%, and 2%; and cancer in 8%, 3%, 1%, and 7%. Overall, 63 patients (32%) had preinvasive or invasive lesions. CONCLUSIONS Atypical glandular cells of undetermined significance on Papanicolaou smears were correlated with significant findings in 45% of patients (32% with preinvasive or invasive lesions and 13% with benign lesions). A prompt and aggressive workup is recommended.

Sentinel node biopsy in vulvar and vaginal melanoma: presentation of six cases and a literature review.

BackgroundUrogenital melanoma is a rare neoplasm with poor prognosis. Its management in the past involved radical vulvectomy and complete bilateral inguinofemoral lymphadenectomy. Sentinel lymph node biopsy is an accurate low-morbidity procedure when used in the context of cutaneous melanoma. However, prophylactic lymphadenectomy has not been shown to improve survival of melanoma patients. We wanted to determine the feasibility of sentinel lymph node biopsy in patients with female urogenital melanoma as a staging procedure.MethodsSix patients with vulvar or vaginal melanomas underwent preoperative lymphatic mapping with99mTc-labeled sulfur colloid followed by sentinel lymphadenectomy. In addition, we reviewed the literature on the application of sentinel lymph node biopsy in urogenital tract melanomas.ResultsOne or more sentinel nodes were identified in all six patients by lymphoscintigraphy. All patients underwent sentinel lymphadenectomy, except for one patient with a deep vaginal melanoma that drained to pelvic nodes. The five successful cases had unilateral drainage patterns. None of the sentinel lymph nodes excised had tumor invasion. Combined with five other patients from the published literature, the success rate of localizing sentinel lymph nodes in the patients with urogenital melanoma approaches 100%.ConclusionsThis experience, plus reports of a small number of patients from three similar studies, supports the impression that sentinel lymph node biopsy is feasible for vulvar and vaginal melanoma.

Effects of Adjunctive Swedish Massage and Vibration Therapy on Short-Term Postoperative Outcomes: A Randomized, Controlled Trial

OBJECTIVE To examine the effects of adjunctive postoperative massage and vibration therapy on short-term postsurgical pain, negative affect, and physiologic stress reactivity. DESIGN Prospective, randomized controlled trial. The treatment groups were: (1) usual postoperative care (UC); (2) UC plus massage therapy; or (3) UC plus vibration therapy. SETTING The University of Virginia Hospital Surgical Units, Gynecology-Oncology Clinic, and General Clinical Research Center. SUBJECTS One hundred and five (N = 105) women who underwent an abdominal laparotomy for removal of suspected cancerous lesions. INTERVENTIONS All patients received UC with analgesic medication. Additionally, the massage group received standardized 45-minute sessions of gentle Swedish massage on the 3 consecutive evenings after surgery and the vibration group received 20-minute sessions of inaudible vibration therapy (physiotones) on the 3 consecutive evenings after surgery, as well as additional sessions as desired. OUTCOME MEASURES Sensory pain, affective pain, anxiety, distress, analgesic use, systolic blood pressure, 24-hour urine free cortisol, number of postoperative complications, and days of hospitalization. RESULTS On the day of surgery, massage was more effective than UC for affective (p = 0.0244) and sensory pain (p = 0.0428), and better than vibration for affective pain (p = 0.0015). On postoperative day 2, massage was more effective than UC for distress (p = 0.0085), and better than vibration for sensory pain (p = 0.0085). Vibration was also more effective than UC for sensory pain (p = 0.0090) and distress (p = .0090). However, after controlling for multiple comparisons and multiple outcomes, no significant differences were found. CONCLUSIONS Gentle Swedish massage applied postoperatively may have minor effects on short-term sensory pain, affective pain, and distress among women undergoing an abdominal laparotomy for removal of suspected malignant tissues.

Well-differentiated endometrial adenocarcinomas and poorly differentiated mixed mullerian tumors have altered ER and PR isoform expression

Both the estrogen receptor (ER) and the progesterone receptor (PR) have two subtypes: ER-α and β, and PR-A and -B, respectively. These subtypes differ in function and expression, and recent reports have correlated changes in the normal proportions of these isoforms with neoplastic states. We investigated ER and PR isoform expression in normal pre- and post-menopausal endometrium, well-differentiated endometrial adenocarcinoma, and poorly differentiated malignant mixed mullerian tumors (MMMTs). Semi-quantitative RT–PCR and immunoblotting were used to measure receptor mRNA and protein expression. Estrogen receptor-α/β mRNA ratios were significantly higher in postmenopausal (27.3) compared to premenopausal endometrium (4.9) mainly as a result of lower ER-β expression in the former. Compared to age-matched postmenopausal controls, the ER-α/β ratio was reduced in both grade I adenocarcinoma and MMMT specimens (3.3 and 6.8, respectively), due to a selective loss of ER-α. The relative abundance of PR-A and PR-B mRNA remained unchanged between all tissue subtypes. Total PR protein, however, was significantly reduced in MMMTs compared to all other groups. Thus, sex steroid receptor expression is significantly and differentially altered in well-differentiated and poorly-differentiated endometrial cancers. Both cancers exhibit decreased ER-α expression and the MMMTs also demonstrate a significant loss of PR protein.

Preoperative hypoalbuminemia is an independent predictor of poor perioperative outcomes in women undergoing open surgery for gynecologic malignancies.

OBJECTIVE To quantify the impact of preoperative hypoalbuminemia on 30-day mortality and morbidity after gynecologic cancer surgery. METHODS Patients included in the National Surgical Quality Improvement Program (NSQIP) dataset who underwent any non-emergent surgery for gynecologic malignancy between 1/1/2008 and 12/31/2010 were identified. Analysis was conducted with albumin both as a dichotomous variable (<3.5 g/dl was defined as low albumin) and as a continuous variable to determine a clinically relevant cut-off value. RESULTS Of the total 3171 patients identified, 2110 had preoperative albumin levels available for analysis. In addition, 279 (13.3%) of these patients had low albumin levels. According to multivariate analysis, the low albumin group had significantly higher odds of developing one or more post-operative complications (OR-2,CI: 1.47-2.73, p<0.0001), three or more complications (OR-4.1,CI: 2.31-7.1, p<0.0001), surgical complications (OR-2.39,CI: 1.59-3.58, p<0.0001), thromboembolic complications (OR-2.59,CI: 1.33-5.06, p<0.0001), pulmonary complications (OR-4.06,CI: 2.05-8.03, p<0.0001), or infectious complications (OR-1.84,CI: 1.26-2.69, p<0.0001) and a higher 30-day mortality (OR-6.52,CI: 2.51-16.95, p<0.0001). Upon subgroup analysis, this difference was not found in patients undergoing laparoscopic surgery. In patients undergoing open surgery, the probability of experiencing one or more post-operative complications increased linearly with the decrease in albumin level; however, the probability of patients experiencing three or more complications and 30-day mortality increased sharply as soon as the albumin level decreased below 3g/dl. CONCLUSION Preoperative albumin levels <3g/dL identify a population of patients at a very high-risk of experiencing perioperative morbidity and 30-day mortality after open surgery.
