RESUMEN

AIMS: Fractures of the distal femur are an important cause of morbidity. Their optimal management remains controversial. Contemporary implants include angular-stable anatomical locking plates and locked intramedullary nails (IMNs). We compared the long-term patient-reported functional outcome of fixation of fractures of the distal femur using these two methods of treatment. PATIENTS AND METHODS: A total of 297 patients were retrospectively identified from a State-wide trauma registry in Australia: 195 had been treated with a locking plate and 102 with an IMN. Baseline characteristics of the patients and their fractures were recorded. Health-related quality-of-life, functional and radiographic outcomes were compared using mixed effects regression models at six months and one year. RESULTS: There was a clinically relevant and significant difference in quality-of-life at six months in favour of fixation with an IMN (mean difference in EuroQol-5 Dimensions Score (EQ-5D) = 0.12; 95% CI 0.02 to 0.22; p = 0.025). There was weak evidence that this trend continued to one year (mean difference EQ-5D = 0.09; 95% CI -0.01 to 0.19; p = 0.073). There was a significant although very small reduction in angular deformity using an IMN (mean difference -1.02; 95% CI -1.99 to -0.06; p = 0.073). There was no evidence that there was a difference in any other outcomes at any time point. TAKE HOME MESSAGE: IMN may be a superior treatment compared with anatomical locking plates for fractures of the distal femur. These findings are concordant with other data from pilot randomised studies which favour treatment of these fractures with an IMN. This study strongly supports the need for a definitive randomised trial. Cite this article: Bone Joint J 2016;98-B:846-50.

RESUMEN

It was the purpose of this review to document the range, incidence, location and mechanism of injury occurring in the sport of rugby league. Rugby league is a collision sport played in Europe and the Pacific regions including Australia. The sport is well established and has competitions ranging from junior to elite professional. Due to the contact nature of the game, injury is relatively common. The most common injuries are musculotendinous in nature and afflict the lower limb more frequently than elsewhere. Despite the high incidence of minor (sprains/strains) to moderate musculoskeletal injury (fracture, ligament and joint injury) and minor head injuries such as lacerations, nasal fractures and concussions, rare more serious spinal cord and other injuries causing death have also been recorded. The literature on rugby league injury is small but growing and suffers from a lack of consistent definition of what an injury is, thereby causing variability in the nature and incidence/prevalence of injury. Information is lacking on the injury profiles of different age groups. Importantly, there has been little attempt to establish a coordinated injury surveillance program in rugby league in the junior or professional levels. The implementation of such programs would require a universal definition of injury and a focus on important events and competitions. The implementation could provide important information in the identification and prevention of risk factors for injury.

RESUMEN

Quadrilateral space syndrome is an uncommon injury. The true prevalence is unknown because of a lack of literature and possible misdiagnosis. Prevalence may increase as knowledge of the syndrome increases. The case is presented of a recreational triathlete who had a spontaneous onset of quadrilateral space syndrome. The diagnosis was made by physical examination and confirmed with magnetic resonance imaging. A conservative, yet aggressive rehabilitation programme resulted in functional improvement within six weeks. Results have been maintained for eight weeks.

RESUMEN

OBJECTIVE: To assess the benefit of a special elective gynecologic oncology program for Obstetrics and Gynecology (Ob/Gyn) residents. METHODS: We reviewed our housestaff records from July 1992 to June 1998 and the National Residency Matching Program (NRMP) subspeciality match results for gynecologic oncology from its inception in 1994 to 1999. RESULTS: From July 1992 to June 1998, a total of 146 residents participated in our elective program. Of the 104 candidates who went through our program and subsequently participated in the NRMP, 55 (53%) obtained match positions. After completion of the elective, 42 of the 146 residents (29%) did not participate in the NRMP for gynecologic oncology and therefore were not eligible to obtain match appointments. During the study period, there were 255 other residents in the United States who applied for gynecologic oncology fellowship positions through the NRMP and did not participate in our program. Of these 255 candidates, 137 (54%) matched. CONCLUSION: The percentage of residents who went through our program, participated in the NRMP, and obtained fellowships did not differ significantly from the percentage of residents who matched without participating in the program. However, almost one-third of the residents who went through our program did not participate in the NRMP. The reasons for their lack of participation were not formally evaluated, but are likely related to a personal decision to pursue another carrer pathway, a decision facilitiated by their experience in our program. Therefore, it appears that the main benefits of the program are to help potential candidates decide whether or not to pursue a career in gyencologic oncology and to aid fellowship programs in identifying exceptional candidates for subspecialty training.

RESUMEN

Radical abdominal hysterectomy and pelvic lymphadenectomy remain the gold standard procedures for the treatment of early cervical cancer. Over the years, the establishment of formal gynecologic oncology training programs, general medical advancements, and new surgical techniques have resulted in a satisfactory tumor resection, with improved overall therapeutic index and reliable cure rates. The role of neoadjuvant and adjuvant therapy continues to be defined as the results from randomized trials emerge.

RESUMEN

OBJECTIVE: The Gynecologic Oncology Group (GOG) has demonstrated that age, tumor grade, and size and number of residual lesions after primary cytoreductive surgery are significant prognostic factors in advanced ovarian carcinoma. Recent studies have reported numerous other clinical features as having prognostic value. We sought to identify the independent prognostic factors for survival in a cohort of patients with advanced ovarian cancer. METHODS: We performed a retrospective chart review of all patients with stage III and IV ovarian carcinoma who received their primary treatment at our institution between 1987 and 1994. RESULTS: A total of 295 patients were identified, 282 of whom were evaluable. Of these 282 patients, 214 (76%) have died of disease or other causes. The median follow-up is 32 months (range: 1-139). Eighteen factors were evaluated for prognostic significance. Significant factors in univariate analysis included patient age, gravidity (0 vs > 0), parity (0 vs > 0), preoperative albumin level, preoperative total protein level, ascites (presence vs absence), disease stage (IIIA/IIIB vs IIIC vs IV), number of residual lesions (< or =20 vs >20), and diameter of largest residual tumor nodule (< or = 1 cm vs 1-2 cm vs > 2 cm). However, on multivariate analysis, only patient age (P < 0.001), ascites (P = 0.001), and size of residual disease (P = 0.005) retained prognostic significance. Substage of disease was of borderline significance (P = 0.086). CONCLUSION: Although numerous clinical variables have recently been reported to have prognostic value in advanced ovarian carcinoma, only patient age, presence or absence of ascites, and diameter of the largest residual tumor nodule proved to be of statistical significance in our analysis.

RESUMEN

OBJECTIVE: Laparoscopically assisted vaginal hysterectomy (LAVH) has evolved into an alternative form of surgical management in the treatment of low-risk endometrial cancer. The purpose of this study was to determine whether low-risk endometrial cancer patients are subject to a higher incidence of positive peritoneal cytology when treated with LAVH compared to total abdominal hysterectomy (TAH). METHODS: We retrospectively reviewed the medical records of patients with low-risk endometrial cancer (grade 1--2 endometrioid type with no evidence of extrauterine spread or grade 3 with <50% myometrial invasion (MI), no cervical or adnexal involvement, and negative lymph nodes when sampled) treated at Memorial Sloan-Kettering Cancer Center from January 1993 to September 1999. We compared 131 patients treated with LAVH to 246 controls who underwent TAH. The two groups were compared for known prognostic factors including grade, MI, vascular space involvement, and lower uterine segment extension. RESULTS: The mean age of patients who underwent LAVH (61 years) was similar to that of the controls (62 years). Fourteen (10.3%) of the patients treated with LAVH had positive peritoneal cytology compared to only 7 (2.8%) of the control population. Factors including FIGO grade, myometrial invasion, and preoperative hysteroscopy did not influence the final results. When stratifying for these factors, the odds ratios of having positive peritoneal washings in those patients treated by LAVH were 5.2, 5.2, and 3.7, respectively. CONCLUSION: Treatment of low-risk endometrial cancer by LAVH is associated with a significantly higher incidence of positive peritoneal cytology. This may be due to the retrograde dissemination of cancer cells into the peritoneal cavity during uterine manipulation. The clinical significance of these findings is yet to be determined.

RESUMEN

BACKGROUND: The aim of this study was to evaluate the accuracy and safety of laparoscopic second-look operations in patients with ovarian cancer. METHODS: We retrospectively reviewed the medical records of all patients who have undergone laparoscopic second-look procedures for ovarian cancer at our institution. RESULTS: From July 1993 to December 1998, 150 patients underwent laparoscopic second-look operations. The mean age of patients was 53 years (range, 25-78 years). The majority of patients (87%) had Stage III or IV disease at initial surgery; the remainder were Stage II or unstaged. Eighty-two patients (54%) had had optimal cytoreduction at the time of their initial surgery. All patients had completed primary chemotherapy and were clinically disease-free based on imaging studies and CA-125 levels at the time of second look. Sixty-nine patients (46%) were found to have pathologically negative second looks; thus, the rate of positive second-look evaluations was 54%. The rate of conversion to laparotomy was 18/150 (12%). In 3 cases this was secondary to bowel injury; one patient sustained a bladder injury; the remainder of conversions to laparotomy were for secondary cytoreduction. There was only 1 case where the patient was found to have extensive adhesions and laparoscopy was abandoned. The overall rate of major complications was 2.7%. CONCLUSIONS: In our experience, laparoscopy is a safe and accurate method of second-look assessment in patients with ovarian cancer. The incidence of complications is low, particularly in this group of patients, all of whom have undergone prior abdominal surgery. The rate of negative evaluations and the rate of recurrences in patients with negative second looks are equivalent to those described in studies of second-look assessment by laparotomy.

RESUMEN

In the United States, ovarian cancer is the fifth most common cause of female cancer death behind lung, breast, colorectal, and pancreatic cancers. It is estimated that 14,500 women in the United States will die of ovarian cancer in 1999 (1). Epithelial ovarian carcinoma accounts for 90% of all ovarian cancers and an even greater percentage of ovarian cancer mortality (2). In this chapter, we will review the role of primary surgery in the management of epithelial ovarian carcinoma. A brief discussion of interval cytoreduction is also included.

RESUMEN

PURPOSE: To determine the frequency of developing abnormal pathologic changes in the endometria of tamoxifen-treated women. To characterize the type of pathologic changes involved. PATIENTS AND METHODS: Between October 1991 and September 1998, 159 patients initiating tamoxifen therapy for breast cancer confined to the breast and axillary lymph nodes were entered in a prospective study. In this study, office endometrial biopsies (EMBs) were obtained during the initiation of tamoxifen and at 6-month intervals for a 2-year period. Three subsequent annual EMBs were recorded for each patient, amounting to a 5-year surveillance. RESULTS: One hundred fifty-nine patients with a median age of 50 years were entered onto study. Patients were assessable if EMBs were performed at least 1 year after the initiation of tamoxifen treatment. Nine patients (5. 7%) were considered protocol violations. The remaining 111 assessable patients underwent a total of 635 EMBs (mean, 5.8 EMBs), with a median surveillance time of 36 months. Eighty-two (12.9%) of the 635 biopsies revealed tissue insufficient for diagnosis. Fourteen patients (12.6%) underwent dilation and curettage (D&C) for an abnormal EMB, persistent bleeding, or for evaluation of adnexal masses at the time of laparoscopy. Findings at D&C included complex hyperplasia (n = 1), abnormal histiocytes (n = 1), simple hyperplasia (n = 2), polyps (n = 4), endocervical polyp (n = 1), and decidualization (n = 2). Three D&Cs were negative. Three patients have undergone hysterectomy. CONCLUSION: EMB was used to monitor the endometrium in the majority (95%) of breast cancer patients on tamoxifen in this trial, but the utility of routine EMB for screening in tamoxifen-treated women seems limited.

RESUMEN

OBJECTIVE: The aim of this study was to review the complications associated with continent urinary diversion and associated procedures in patients with gynecologic malignancies. METHODS: We retrospectively reviewed the medical records of all patients who underwent construction of a continent urinary conduit between October 1991 and October 1998 on the Gynecology Service at Memorial Sloan-Kettering Cancer Center. RESULTS: Thirty-three patients were identified, of whom 22 underwent total pelvic exenteration, 8 underwent anterior exenteration, and 3 underwent urinary diversion procedures only. Complications associated with the urinary diversion procedure included ureteral strictures (2), pouch leakage (2), mild hydronephrosis, (6), pyelopnephritis (2), nocturnal incontinence (5), and difficulty with self-catheterization (2). Additional procedures performed concomitantly with continent urinary diversion and exenteration included pelvic reconstruction (18), low-rectal anastomosis (13), and intraoperative radiation therapy (9). The most significant morbidity was seen in patients undergoing concomitant low-rectal anastomosis, in whom the rate of anastomotic leaks was 54% (7 of 13 patients). CONCLUSIONS: Continent urinary diversion can successfully be accomplished at the time of exenteration in patients with recurrent gynecologic malignancies. The rate of major complications related to the urinary diversion is small and most complications can be managed nonsurgically. The greater than 50% rate of anastomotic leaks in patients undergoing concomitant low-rectal anastamosis suggests that such anastomosis should not be undertaken in this group of patients.

RESUMEN

CONTEXT: Most hereditary ovarian cancers are associated with germline mutations in BRCA1 or BRCA2. Attempts to define the clinical significance of BRCA mutation status in ovarian cancer have produced conflicting results, especially regarding survival. OBJECTIVE: To determine whether hereditary ovarian cancers have distinct clinical and pathological features compared with sporadic (nonhereditary) ovarian cancers. DESIGN AND SETTING: Retrospective cohort study of a consecutive series of 933 ovarian cancers diagnosed and treated at our institution, which is a comprehensive cancer center as designated by the National Cancer Institute, over a 12-year period (December 1986 to August 1998). PATIENTS: The study was restricted to patients of Jewish origin because of the ease of BRCA1 and BRCA2 genotyping in this ethnic group. From the 189 patients who identified themselves as Jewish, 88 hereditary cases were identified with the presence of a germline founder mutation in BRCA1 or BRCA2. The remaining 101 cases from the same series not associated with a BRCA mutation and 2 additional groups (Gynecologic Oncology Group protocols 52 and 111) with ovarian cancer from clinical trials (for the survival analysis) were included for comparison. MAIN OUTCOME MEASURES: Age at diagnosis, surgical stage, histologic cell type and grade, and surgical outcome; and response to chemotherapy and survival for advanced-stage (II and IV) cases. RESULTS: Hereditary cancers were rarely diagnosed before age 40 years and were common after age 60 years, with mean age at diagnosis being significantly younger for BRCA1- vs BRCA2-linked patients (54 vs 62 years; P=.04). Histology, grade, stage, and success of cytoreductive surgery were similar for hereditary and sporadic cases. The hereditary group had a longer disease-free interval following primary chemotherapy in comparison with the nonhereditary group, with a median time to recurrence of 14 months and 7 months, respectively (P<.001). Those with hereditary cancers had improved survival compared with the nonhereditary group (P=.004). For stage III cancers, BRCA mutation status was an independent prognostic variable (P=.03). CONCLUSIONS: Although BRCA-associated hereditary ovarian cancers in this population have surgical and pathological characteristics similar to those of sporadic cancers, advanced-stage hereditary cancer patients survive longer than nonhereditary cancer patients. Age penetrance is greater for BRCA1-linked than for BRCA2-linked cancers in this population.

RESUMEN

Preclinical studies have demonstrated a relationship between DNA mismatch repair (MMR) status and sensitivity to cisplatin and carboplatin. MMR-deficient cells are resistant to both drugs, and selection for cisplatin resistance in vitro is sometimes accompanied by loss of MMR protein expression. We used immunohistochemical staining techniques to investigate hMLH1 and hMSH2 expression in paired ovarian tumor sections from 54 ovarian cancer patients before and after platinum-based therapy. We sought associations between hMLH1 and hMSH2 protein expression and clinical parameters known to be of prognostic significance as well as response to treatment and overall survival. hMLH1 and hMSH2 staining decreased significantly after platinum-based therapy. The percent of malignant cells that stained positive correlated with the intensity of nuclear staining for both proteins; staining for hMLH1 correlated well with staining for hMSH2. Unexpectedly, expression of nuclear hMLH1 correlated negatively with response to treatment. Expression of nuclear hMLH1 and hMSH2 was positively correlated with pretreatment CA125 level, and expression of nuclear hMSH2 was positively correlated with change in CA125 level after treatment. Tumor stage was associated with expression of nuclear hMSH2, and tumor histological subtype was associated with both hMLH1 and hMSH2 staining. No association was found between expression of either protein and overall survival. These results indicate that the tumor is biologically altered after chemotherapy consistent with treatment-induced selection for cells expressing lower hMLH1 and hMSH2 levels. However, immunohistochemical staining for either hMLH1 or hMSH2 was not highly predictive of drug sensitivity as measured by response or survival.

RESUMEN

PURPOSE: The aim of this study was to determine the ability of preoperative serum CA-125 to predict optimal primary tumor cytoreduction in patients with Stage III epithelial ovarian carcinoma. METHODS: We performed a retrospective chart review of 100 consecutive patients with Stage III ovarian carcinoma who had a serum CA-125 drawn prior to primary cytoreductive surgery. We used a receiver operating characteristic curve to determine the CA-125 level with the maximal prognostic power in predicting optimal versus suboptimal cytoreduction. RESULTS: The median CA-125 level for the 100 patients was 819 U/ml (range 5.6-26,200 U/ml). Optimal cytoreduction (diameter of largest residual tumor nodule < or =1 cm) was obtained in 45 cases (45%). The probability of performing optimal cytoreduction decreased with increasing CA-125 levels. A preoperative CA-125 level of 500 U/ml was identified as the value with the most predictive power. Optimal cytoreduction was achieved in 33 of the 45 cases (73%) with a CA-125 less than 500 U/ml compared to only 12 of the 55 cases (22%) with a CA-125 greater than 500 U/ml. Using a threshold level of 500 U/ml, the preoperative serum CA-125 level was able to predict optimal versus suboptimal cytoreduction with a sensitivity of 78%, specificity of 73%, positive predictive value of 78%, and negative predictive value of 73%. CONCLUSION: The probability of performing optimal cytoreduction in patients with Stage III ovarian carcinoma and a preoperative CA-125 greater than 500 U/ml was approximately one in five. These patients may be candidates for initial laparoscopic evaluation to obtain a confirmatory tissue diagnosis and to determine resectability.

RESUMEN

Cancer of the uterine cervix is the seventh most common malignancy among women and the fifth most common cause of cancer mortality worldwide. In the United States, the use of the Papanicolaou (Pap) smear for screening has meant a significant decline in the incidence and mortality from cervical cancer over the past five decades. However, there are still approximately 12,800 new cases diagnosed per year in the U.S. and 4,800 deaths are estimated in 1999. Both surgery and radiation therapy have long-established roles in management. Surgery has the advantages of shorter treatment time, removal of the primary tumor, more limited tissue injury, and the potential to preserve ovarian function; radiation therapy has the capacity to treat tumor that involves the bladder and/or rectum while preserving their function. Therefore, the role of surgery is more suited to the management of early-stage disease and centrally located recurrences that occur after radiation therapy. Studies from our institution have played an integral role in the development of the modern surgical approach to cervical cancer. Reviews on early-stage disease helped define the role of conization and simple hysterectomy for microinvasive cervical cancer and identified patients who were at high risk for recurrence after radical hysterectomy. The classic work of Brunschwig has given gynecologic surgeons the ability to offer hope and life to select patients who previously could have expected only pain and death. Future investigation into the techniques of intra-operative radiation therapy may increase the pool of patients for whom surgically based salvage therapy may be offered.

RESUMEN

OBJECTIVE: The aim of this study was to determine the feasibility and efficacy of intraperitoneal cisplatin and mitoxantrone in patients with very small-volume residual disease at second-look surgery after completion of primary platinum-based intravenous chemotherapy. PATIENTS AND METHODS: Between February 1992 and February 1994, 42 patients were treated with up to five cycles of intraperitoneal cisplatin (100 mg/m2)/mitoxantrone (10 mg/m2). Patients were evaluated for surgically defined response rate and followed for progression-free (PFS) and overall survival (OS) using an intention-to-treat analysis, and grouped according to disease volume at initiation of treatment. RESULTS: The mean age of all patients was 48.5 years. Thirty patients (71%) were Stage III at diagnosis; 18 patients (43%) had microscopic disease at the initiation of IP therapy, and 24 patients (57%) had macroscopic disease. Twenty-eight patients completed three or more cycles of protocol therapy, and 14 patients were changed to standard intravenous therapy after receiving fewer than three cycles of treatment secondary to catheter-related problems (12 patients), cisplatin ototoxicity (1 patient), or withdrawal from study (1 patient). Using an intention-to-treat analysis, the median PFS was 22.5 months, and the median OS of all patients (N = 42) was 47 months (6-72 months) with a median follow-up of 62.7 months. When grouped according to size of disease at initiation of treatment, the OS has not been reached at 62.7 months of follow-up in patients (N = 18) with microscopic disease. CONCLUSIONS: (1) The combination of IP mitoxantrone and cisplatin has an unacceptable catheter failure rate due to mitoxantrone toxicity; (2) PFS and OS is longer in patients with microscopic rather than macroscopic residual disease; and (3) intraperitoneal platinum-based chemotherapy in patients with very small-volume residual disease may result in improved survival.

RESUMEN

PURPOSE: To assess CA-125 as a measure of response in patients treated with paclitaxel. PATIENTS AND METHODS: One hundred forty-four patients treated with paclitaxel derived from four different trials and 625 patients treated with platinum from two trials were analyzed using precisely defined 50% and 75% reductions in CA-125. The standard and CA-125 response rates to paclitaxel and platinum were compared. In addition, we analyzed individual patient groups in which there was a difference in response according to the two response criteria. RESULTS: Patients with stable disease as determined by standard criteria who were treated with platinum and responded according to CA-125 criteria have an improved median progression-free survival compared with patients with stable disease who did not respond according to CA-125 criteria (10.6 v 4.8 months; P<.001). Standard and CA-125 response rates for patients treated with platinum (58.93% v 61.31%, respectively) and paclitaxel (30.65% v 31.67%, respectively) were very similar, as were rates of false-positive prediction of response by CA-125 (platinum 2.2% and paclitaxel 2.9%). Responders to paclitaxel had a significantly improved progression-free survival compared with non-responders by both standard criteria (median progression-free survival, 6.8 v 2.5 months; P<.001) and CA-125 criteria (median progression-free survival, 6.8 v 3.4 months; P<.001). CONCLUSION: Forassessing activity of therapy for ovarian cancer, these data show that precise 50% or 75% CA-125 response criteria are as sensitive as standard response criteria. We propose that they may be used as a measure of response in lieu of or in addition to standard response criteria in clinical trials involving epithelial ovarian cancer. Sensitivity is maintained whether patients are treated with platinum or paclitaxel.

RESUMEN

OBJECTIVE: To determine long-term survival and predictors of recurrence in patients with platinum-treated ovarian cancer who were followed for 10 years after second-look laparotomy with negative findings. METHODS: Records were reviewed of 91 consecutive patients with negative findings on second-look laparotomy after platinum-based chemotherapy between January 1978 and January 1987. Statistical analysis used Kaplan-Meier survival curves, Cox proportional hazards, and multiple logistic regression. RESULTS: Mean age of patients was 57 (range 30-79) years. Distribution by stage and grade was as follows: stage I, ten; II, 18; III, 57; IV, six; grade 1, 18; 2, 28; 3, 45. Forty-seven of 91 women had optimal initial cytoreduction. Recurrence-free survival rates for all subjects were 75% at 2 years, 55% at 5 years, and 52% at 10 years. For women with stage I disease, the recurrence-free survival rate was 90% at 2, 5, and 10 years. For women with stage II disease, recurrence-free survival rates were 78, 72, and 66% at 2, 5, and 10 years, respectively. Patients with stage III or IV disease had recurrence-free survival rates of 72, 44, and 40% at 2, 5, and 10 years, respectively. Risk of recurrent disease was related to tumor stage (relative risk [RR] 2.02; 95% confidence interval [CI] 1.2, 3.3; P = .005), grade (RR 2.00; 95% CI 1.3, 3.2; P = .004), and presence of a residual tumor of more than 2 cm at the end of initial surgery (RR 3.19; 95% CI 1.2, 8.5; P = .02). CONCLUSION: Ovarian cancer patients face an appreciable risk of recurrence in the first 5 years after second-look laparotomy with negative findings after platinum-based chemotherapy, but those who remain disease free at 5 years have excellent long-term survival rates. Tumor stage, grade, and presence of a residual tumor of more than 2 cm after initial surgery are significant predictors of recurrence.
