Vacuum-assisted closure in the treatment of gynecologic oncology wound failures.

OBJECTIVE: Negative pressure wound vacuum therapy can expedite the healing of complex wound failures. Our aim was to evaluate the use of a vacuum-assisted closure (VAC) device to treat complex wound failures in gynecologic oncology patients. METHODS: We retrospectively identified 27 patients with gynecologic malignancies in whom the device was used to treat complex wound failures from January 2001 to May 2002 at our institution. We analyzed operative data and information regarding the diagnosis and management of these complex wound failures and the length of time the device was used. RESULTS: The procedures performed before wound VAC placement were total abdominal hysterectomy with bilateral salpingo-oopherectomy with or without tumor reductive surgery in 14 patients, vulvectomy with or without inguinal lymph node dissection in five patients, skin or myocutaneous grafting in three patients, parastomal herniorrhaphy in two patients, retroperitoneal lymph node dissection in two patients, and incision and drainage of a gluteal abscess after radiation therapy in one patient. Four of the 27 patients had the VAC device placed at the time of a reoperation, while the remaining 23 patients had the VAC device placed postoperatively for wound failures. Wound breakdown occurred at a median of 9 days (range: 0-88 days) postoperatively. Overall, there was a 96% reduction (range: 0-100%) in the median size of wound defects from 330 to 14.0 cm(3) with use of the VAC device. The median number of days of VAC therapy was 32 days (range: 3-88 days). Twenty patients used this device as outpatients, and the charge per day was approximately US$150.00. One patient experienced bleeding, and 26 patients experienced no complications. The only complaint was pain during dressing changes (67% of patients). The mean follow-up was 52 days (range: 0-270 days). At the time of last contact, 26 (96%) of 27 patients had complete wound healing. CONCLUSIONS: VAC therapy is a novel treatment using controlled negative pressure to evacuate wound fluid, stimulate granulation tissue, and to decrease bacterial colonization of the wound. Our experience indicates that this is a safe method to treat complex wound failures in gynecologic oncology patients.

Lymphocele after retroperitoneal node dissection for testis tumor.

A patient is presented in whom a lymphocele developed after a retroperitoneal lymph node dissection for Stage II embryonal carcinoma of the testicle. The benign nature of this lymphocele has been confirmed not only by the diagnostic procedures outlined, but by its stability over a 42-month follow-up period with no further antitumor therapy. We conclude from reviewing the literature that while aggressive measures are necessary to confirm the diagnosis of a lymphocele, its management should be expectant. If significant obstruction of neighboring structures occurs, an attempt at percutaneous drainage (and possibly sclerosis) seems appropriate despite potential risks of interventional treatment such as hemorrhage and introduction of infection. Open procedures for marsupialization and drainage should be reserved for cases in which more conservative measures fail.

Distribution of nodal metastases after chemotherapy in nonseminomatous testis cancer: a possible indication for limited dissection.

OBJECTIVE: To assess the clinical and pathological findings of patients treated by bilateral retroperitoneal lymph node dissection (RPLND) after chemotherapy, to identify a subset for whom modified template nodal resection might be contemplated, as bilateral RPLND is the treatment of choice in patients with residual retroperitoneal disease after chemotherapy for nonseminomatous germ-cell tumour (GCT). PATIENTS AND METHODS: The medical records were reviewed of 50 consecutive patients who had RPLND after chemotherapy between 1996 and 2005. Bilateral template RPLND was performed uniformly. Extracted lymph nodes were surgically stratified into three distinct anatomical zones by two sagittal planes running in front of the aorta and the inferior vena cava. The pathological findings were correlated with the side of the primary lesion and the extent of metastatic disease before chemotherapy. RESULTS: Pathological assessment of the resected lymph nodes revealed teratoma in 28 patients (56%), viable carcinoma in three (6%), and necrosis or fibrosis in 19 (38%). All clinical stage Is, IIA and IIB left-sided primary tumours followed a predictable pattern of spread constricted to a modified left-sided template. Patients with clinical stage IIC and III, or right-sided primary tumour, had a less predictable metastatic pattern, having crossover metastases to the contralateral template. CONCLUSION: Bilateral RPLND should be considered as the reference standard in patients with metastatic GCT and residual retroperitoneal mass after completing chemotherapy. However, the present data suggest that a modified template dissection might be considered even after chemotherapy in patients with left-sided primary tumours and limited nodal involvement at presentation.

CT detection of retroperitoneal lymph node metastases in patients with clinical stage I testicular nonseminomatous germ cell cancer: assessment of size and distribution criteria.

OBJECTIVE: Patients with nonseminomatous germ cell cancer of the testis with no evidence of metastatic disease after orchiectomy may be managed with either retroperitoneal lymph node dissection or surveillance. The present retrospective study was undertaken to determine the accuracy of CT for revealing retroperitoneal lymph node metastases in patients with newly diagnosed clinical stage 1 testicular nonseminomatous germ cell cancer of the testis when smaller size criteria (smaller than 10 mm) are applied and to test the hypothesis that CT-revealed anterior retroperitoneal lymph nodes are more likely to correlate with metastases than are posterior lymph nodes. MATERIALS AND METHODS: Abdominal CT scans obtained before surgery in 70 patients were reviewed by three observers who were unaware of the results of retroperitoneal lymphadenectomy. The sizes and sites of all lymph nodes measuring larger than or equal to 4 mm were recorded. Each CT scan was judged as positive or negative for retroperitoneal metastasis on the basis of the size of the largest measured lymph node at the expected metastatic site. Diameters of 4, 6, 8, and 10 mm were successively applied to each case as the criteria for a positive scan. RESULTS: Using a criterion of 10 mm or larger for metastases, we calculated a sensitivity of 37% and a specificity of 100%; with a 4-mm criterion, the sensitivity was 93% and the specificity was 58%. Receiver operating characteristic curves comparing the accuracy of CT for revealing similar-sized lymph nodes located anterior or posterior to a line bisecting the aorta differed significantly (p = .04) when the same criteria were applied to lymph nodes in both regions. CONCLUSION: False-negative rates were decreased from 63% using a size criterion of 10 mm to as low as 7% using a size criterion of 4 mm, with a corresponding decrease in specificity. Lymph nodes measuring larger than or equal to 4 mm, especially those located anterior to the mid portion of the aorta, should raise a suspicion of metastases.

The role of chemotherapy and surgery in the treatment of retroperitoneal metastases in advanced nonseminomatous testis cancer.

This study evaluates the effect of combination chemotherapy on retroperitoneal metastases from nonseminomatous germ cell tumors of the testis (NSGCTT). Sixty-six patients with Stage III or bulky Stage II NSGCTT with clinically documented retroperitoneal metastases first received systemic chemotherapy. Seventeen patients had minimal and 49 had advanced retroperitoneal metastases. The retroperitoneal metastases were classified as advanced if the patient had a palpable retroperitoneal mass, ureteral deviation on intravenous pyelogram, or a mass with a diameter greater than or equal to 5 cm documented by a computerized axial tomographic scan, a pedal lymphangiogram, or surgery. The patients with lesser but clinically evident retroperitoneal metastatic deposits were considered to have minimal retroperitoneal metastases. A complete remission of retroperitoneal metastatic deposits was achieved in 50 (76%) patients, with chemotherapy alone in 25 (38%), and with combined chemotherapy and surgery in 25 (38%). The resected deposits consisted of mature teratoma in 15 and malignant elements in 10. A complete remission using chemotherapy alone occurred in 13 of 17 (76%) with minimal and in 12/49 (24%) with advanced retroperitoneal metastases, and in 17/30 (57%) without and 8/36 (22%) with teratoma in the testis tumor. The data strongly implied that the bulk of the metastatic deposits was a more important prognostic variable than the histology of the primary tumor. The adverse relationship of a teratomatous differentiation on the response rates with chemotherapy alone was offset by the success of supplemental surgery. This study suggests the benefit of a postchemotherapy retroperitoneal lymph node dissection (RPLND) in patients with initially bulky retroperitoneal metastases (complete response [CR] increased from 24% to 67%; an additional 47% patients had no evidence of disease). The patients with minimal retroperitoneal metastases usually achieved a CR with chemotherapy alone. A routine RPLND after the chemotherapy is not indicated in patients with initially minimal retroperitoneal metastases.

Non-seminomatous testicular cancer clinical stage I: prediction of outcome by histopathological parameters. A multivariate analysis.

The clinical course of 186 orchiectomized patients with testicular non-seminoma clinical stage I (CSI) was reviewed together with a reevaluation of the haematoxylin-eosin-stained histological sections of the primary tumour. Treatment (1970-1980) was as follows: abdominal radiotherapy (group 1): 132 patients; observation only (group 2): 23 patients; retroperitoneal lymph node dissection (group 3): 31 patients. Failure of the management (diagnostic error/relapse after treatment) was defined as demonstration of retroperitoneal lymph node metastases (group 3) or relapse during follow-up (group 2 and 3). Ten of the 31 primarily operated patients had retroperitoneal lymph node metastases. (These patients received 3-4 cycles adjuvant cisplatin based on chemotherapy.) Forty-six patients relapsed after a median time of 6 months (range: 2-113). The 10-year cancer-related survival rates for group 1 and 2 were 85 and 73%, respectively. No cancer-related death occurred in group 3 within the first 5 years. In a univariate analysis the following parameters were significantly (p less than 0.05) correlated with management failure: vascular invasion (blood, lymphatic), the presence of syncytiotrophoblasts, the demonstration of the histological subtype MTU. In a multivariate analysis both lymphatic and blood vessel invasion significantly predicted management failure. In 80% of the non-seminoma patients with CSI and both lymphatic and blood vessels invasion in the primary tumour failure of the primary management must be expected. In the multivariate analysis the demonstration of MTU was a predictive factor only if no differentiation was made between lymphatic and blood vessel invasion. The presence or absence of endodermal sinus tumour was not correlated with the failure rate in non-seminoma CSI. Based on easily assessable histopathological parameters of the primary tumour (small vessel invasion in particular) it is possible to define subgroups of patients with non-seminoma CSI who have a high or a low risk of relapse or who are likely to have microscopic retroperitoneal lymph node metastases. Such a differentiation should have therapeutic consequences.

Retroperitoneal node biopsy in paratesticular rhabdomyosarcoma.

UNLABELLED: Retroperitoneal lymph node dissection (RPLND) was used in 121 Intergroup Rhabdomyosarcoma Study (IRS) III patients with nonmetastatic paratesticular (PT) rhabdomyosarcoma (RMS) to assess retroperitoneal lymph node (RPLN) involvement so as to determine the need for x-ray therapy (XRT). Clinical node evaluation (CNE) was accomplished by a computed tomography (CT) scan in 105 and a sonogram in six. Pathological node evaluation (PNE) was performed in 113: lymphadenectomy (9 bilateral, 85 unilateral) and biopsy in 19. Vincristine and actinomycin D were used for 1 year postoperatively in 89%; all patients who had positive PNE received RPLN XRT. This study compares CNE with PNE and evaluates predictors of relapse and survival. FINDINGS: There were clinically negative nodes (cN0) in 81% of the 121 patients. Among cN0 patients, 14% had positive nodes (pN1). Of the clinically positive (cN1) patients, 94% had pN1. RPLN relapse occurred in only two of the 121 patients. Initially both had cN0 and one had PNE that was negative. For all 121 patients, the 5-year survival was 91%. For cN0 patients, the 5-year survival was 96% compared with 69% for cN1 patients (P < .001). Among the children in whom treatment failed, nodes were cN1 in 5 of 11 (45%) compared with 15 of 107 (14%) in those whose treatment did not fail (P < .008). CONCLUSIONS: (1) Results of RPLN imaging studies were negative in 81% of patients with PT RMS (specificity 99%, sensitivity 57%). (2) RPLN recurrence is uncommon (even when RPLN are initially involved) if regional XRT and appropriate chemotherapy are used.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical stage 1 testicular cancer: the role of modified retroperitoneal lymphadenectomy.

A total of 85 patients underwent modified retroperitoneal lymphadenectomy for clinical stage I nonseminomatous germ cell tumor of the testis from 1982 to 1989. The technique was a modified bilateral dissection via a thoracoabdominal approach. A full bilateral dissection was done above the level of the inferior mesenteric artery but unilateral dissection was performed below the inferior mesenteric artery using a template method. Of the 85 patients 64 had pathological stage A and 21 had stage B1 disease. Relapses have occurred in 4 of 64 stage A cancer patients (6%) and 3 of 21 stage B1 cancer patients (15%). Antegrade ejaculation was preserved without pharmacological therapy in 75 of 85 patients (88%) and 5 others were converted to antegrade ejaculation with imipramine. Therefore, 80 of 85 patients (94%) have recovered antegrade ejaculation. With a median followup of 38 months 7 relapses have been noted. We conclude that modified retroperitoneal lymph node dissection allows for preservation of ejaculation, decreases concern about retroperitoneal understaging and represents the preferred alternative to surveillance protocols for patients with low stage testicular cancer.

Retroperitoneal anomalies in men with testicular germ cell tumours.

OBJECTIVES: To assess whether vascular and other retroperitoneal anomalies are more frequent during retroperitoneal lymph node dissection (RPLND) for metastatic testicular tumours (when retroperitoneal masses persist after chemotherapy) than would be expected, based on the initial observations from one centre with a large experience of RPLND in the UK. PATIENTS AND METHODS: A prospective series of 278 consecutive patients treated with RPLND for testicular tumours comprised the sample population. For each patient the presence or absence of four factors from the history was recorded. Each patient then underwent RPLND. During surgery, a template was constructed of the anatomy of the retroperitoneum and the information stored. Eight different retroperitoneal anatomical anomalies were identified in the sample population; the incidence of each was then compared with the largest available study of a normal population, and differences analysed statistically. RESULTS: Of the 278 patients who had RPLND, 55 had 59 anomalies (21%), found by history and as retroperitoneal vascular and urological anomalies; cryptorchidism was present in 7.6%, 9.5 times the incidence in the control population (P < 0.01). A left-sided inferior vena cava was present in 3.6% of patients, 21 times the incidence in the control population (P < 0.001); a retro-aortic left renal vein in 3.2%, four times that in the control population (P < 0.05); and ipsilateral renal agenesis had an incidence of 1% in the test population, 11 times greater than in the control population (P < 0.01). CONCLUSIONS: This prospective study of 278 RPLNDs provides evidence that some retroperitoneal anatomical anomalies are associated with testicular germ cell tumours. The link between maldescent and testicular tumours, rather than an isolated association, should be considered as part of a spectrum of retroperitoneal anomalies that occur in these men.

Clinical behavior and a contemporary management algorithm for prepubertal testis tumors: a summary of the Prepubertal Testis Tumor Registry.

PURPOSE: The Prepubertal Testis Tumor Registry was established by the Urologic Section of the American Academy of Pediatrics in 1980 to record data on a large number of prepubertal testis tumors regarding presentation, treatment and outcome to define appropriate management better. We reviewed the registry data in the context of other modern studies to elucidate the appropriate management of these rare tumors. MATERIALS AND METHODS: Relevant data in the prepubertal testis tumor registry were tabulated and analyzed. RESULTS: There were 395 prepubertal patients who had a primary testis tumor. Generally benign tumors accounted for 38% of cases. A significant proportion of tumors were benign regardless of patient age. alpha-Fetoprotein levels for patients with benign and malignant tumors overlapped in children younger than 6 months. Of the patients with yolk sac tumor 80% presented with stage 1 disease and overall survival was excellent. There were no metastases or deaths among the patients with teratoma. Of all patients with stromal tumors metastases developed in only 1. CONCLUSIONS: We recommend initial excisional biopsy for all amenable prepubertal testis tumors, except those with an alpha-fetoprotein level that is clearly increased for patient age. Patients with benign tumors may be released from oncological followup. Patients with stage I yolk sac tumor should be monitored closely, and those with recurrent or metastatic yolk sac tumor should be treated with chemotherapy. Retroperitoneal lymph node dissection is reserved for patients with recurrent retroperitoneal masses following chemotherapy. Aggressive treatment of metastatic Sertoli cell or undifferentiated stromal tumors is warranted.

Inguinal node metastases from testicular tumors in patients with prior orchiopexy.

Testicular tumors in patients who have had the lymphatics disrupted by prior scrotal or inguinal surgery can metastasize primarily to the ipsilateral inguinal nodes in addition to the usual retroperitoneal pattern. Whether routine inguinal node dissection along with retroperitoneal node dissection is warranted in patients with testicular tumors and prior scrotal surgery is controversial due to the small numbers of such cases reported in the literature. We report on 2 patients who had undergone previous orchiopexy and who presented with inguinal and testicular masses. Both patients underwent retroperitoneal lymph node dissection and inguinal node dissection with hemiscrotectomy and metastatic tumor was in each lymphatic area. Ipsilateral inguinal along with bilateral retroperitoneal node dissection should be considered in the primary therapy of any patient with a nonseminomatous testicular tumor who has had prior scrotal and certain inguinal procedures.

Teratoma in the orchiectomy specimen and volume of metastasis are predictors of retroperitoneal teratoma in low stage nonseminomatous testis cancer.

PURPOSE: We determined whether teratomatous elements in the orchiectomy specimen predict for teratoma in the retroperitoneum in patients who have not received chemotherapy. MATERIALS AND METHODS: We retrospectively reviewed the records of patients with clinical stages A, B and B2 nonseminoma who underwent retroperitoneal lymph node dissection. RESULTS: Teratomatous elements in the orchiectomy specimen predict for retroperitoneal teratoma. CONCLUSIONS: When deciding on treatment for low stage nonseminoma, the presence or absence of teratoma in the orchiectomy specimen should be considered to minimize double therapy.

Lymphography in the diagnosis of non-seminoma tumours of the testis.

In a series of 86 lymphograms correlated to histological findings after retroperitoneal lymph node dissection or to laparotomy findings, reliability proved to be 78%. The reliability of lymphograms evaluated as positive was 88%, while that of negative lymphograms was 74%. Retroperitoneal lymph node metastases were detected with the aid of lymphography in 58% of the patients. It was impossible to establish a node size above which metastases could be demonstrated with certainty by lymphography.

Late recurrences of germ cell malignancies: a population-based experience over three decades.

The purpose of this study was to explore the incidence of late relapse in patients with malignant germ cell tumour (MGCT) in a population-based series, with emphasis on the mode of detection, survival, and the relevance of histological findings. The clinical records from a population-based cohort of patients with seminoma (n=1123) or non-seminoma (n=826) were evaluated for late relapses. Twenty-five patients developed a late relapse. The cumulative 10-year incidence rate was 1.3%. All 10 seminoma patients, but only eight of 15 non-seminoma patients relapsed with vital malignant tumour (P=0.02). Teratoma or necrosis was found in seven of nine primarily chemotherapy-treated non-seminoma patients with normal tumour markers at late relapse. Six of nine patients operated with limited retroperitoneal lymph node dissection as part of the primary treatment had relapsed retroperitoneally outside the original operation field. The 10-year cause-specific survival was 68% in all patients, 50% in patients relapsing with vital malignant tumour and 100% in those with teratoma/ necrosis before or after salvage chemotherapy. The 10-year incidence rate of late relapses of 1.3% might reflect the true incidence rate in a population-based cohort of MGCT patients, with cure in at least half of them.

[Study of twenty-three cases of pediatric testicular tumors].

Twenty-three cases of testicular tumor (10; malignant, 13; benign) in childhood are reported. The age at diagnosis was between 3 months old and 8 years old. Twelve patients visited the clinic within a month of first appearance of symptoms. All but one patient received high orchiectomy. One patient had resection of tumor because of its benign property. Eight of the 10 patients with malignancies received 30-50Gy of retroperitoneal radiation, including one patient (stage IIa) with retroperitoneal lymph node dissection. Two patients (stage I and IIa) with post-operative metastasis in lungs, brain and mediastinal lymph nodes were treated with chemotherapy repeatedly, but they died. Our latest therapy is; 1) high orchiectomy recommended for benign and stage I malignant testicular tumors in childhood, 2) retroperitoneal radiation and/or lymph node dissection limited for patients with stage II malignancy, and 3) Systemic chemotherapy for stage III malignant tumors. At least three years of follow up would be needed. Those who received radiation or chemotherapy should be followed longer.

[Laparoscopic retroperitoneal lymph node excision in clinical stage I non-seminomatous testicular cancer].

Modified retroperitoneal lymph node dissection for stage I testicular tumors has been described by Weissbach. For performing laparoscopic retroperitoneal lymphadenectomy within these boundaries, we have developed a two-step procedure. In the first step, a ventral approach is used. The colon is dissected free, then the spermatic vein is excised, and the borders of dissection are defined. Removal of retroaortic and retrocaval nodal tissue is technically not feasible from the ventral approach. Therefore, in the second step, a lateral approach is employed, which is the key to success since it allows for easy transection of the lumbar vessels. Thus complete lymph node dissection can be realized. Between August 1992 and June 1993 this procedure was performed in 11 patients. In 7 patients, the tumor was on the right side and in 4 on the left. Conversion to open surgery was necessary in two patients because of uncontrollable bleeding and a large metastasis, respectively. Microscopic metastases were detected in two other patients. No major complications occurred; no blood transfusions were required. So far, the results have been encouraging.

Laparoscopic retroperitoneal lymphadenectomy for stage I non-seminomatous testicular tumors.

Retroperitoneal lymph node dissection (RPLND) is the most accurate method to evaluate the presence and extent of retroperitoneal nodal metastases in clinical stage I non-seminomatous germ cell testicular carcinoma. In our Department the open "nerve sparing" RPLND is already the standard surgical treatment for these tumors and laparoscopic technique is employed in surgical treatment of digestive diseases as cholelithiasis, hiatal hernias and gastrointestinal tumors; we report our first experience with laparoscopic RPLND in patients with low stage non-seminomatous germ cell testicular tumors (NSGCTT). A laparoscopic modified template RPLND was performed in 5 high-risk patients with non-seminomatous germ cell clinical stage I tumors by a transperitoneal approach. In 4 of the 5 cases a template dissection was performed. In one pathological stage II tumor a limited lymph node dissection was performed and the patient underwent postoperative chemotherapy. Mean operative time was 190 minutes (range 160-210). No retrograde ejaculation occurred. The mean number of dissected nodes was 21 (range 16-25). At mean follow-up of 16.3 months (range 12-21) the 4 operated patients with pathological stage I NSGCTT are disease free without ejaculatory or urinary dysfunction. Our preliminary experience suggests that laparoscopic RPLND for stage I NSGCTT is feasible and safe for surgeons largely trained in either laparoscopic digestive surgery or open RPLND for whom the learning curve of that minimally invasive approach is lower than expected.

Long-term effects on sexual function and fertility after treatment of testicular cancer.

This retrospective study evaluates the types and incidences of sexual disturbances and fertility distress in patients cured from testicular cancer and examines whether there is an effect resulting from different treatment modalities. A self-reported questionnaire was sent to 124 randomly selected patients who were treated at Hanover University Medical School between 1970 and 1993. Ninety-eight patients were included in the study, representing a response rate of 78%. All patients had been in complete remission (CR) for at least 24 months. The median age at diagnosis was 28 years (range 17-44). The median follow-up at the time of study was 12.0 years (range 2.8-25.6). Twenty patients (20%) had been treated for seminomatous and 78 patients (80%) for non-seminomatous germ cell tumours. Treatment included surveillance (7%), primary retroperitoneal lymph node dissection (RPLND) (13%), chemotherapy (CT) (33%), CT + secondary resection of residual retroperitoneal tumour mass (SRRTM) (43%) and infradiaphragmatic radiotherapy (4%). Patients receiving two treatment modalities (CT+SRRTM) reported more frequent an unfulfilled wish for children. Inability of ejaculation was clearly associated with RPLND and SRRTM. Subjective aspects of sexuality, like loss of sexual drive and reduced erectile potential, occurred only in a minority of patients after treatment. No abnormalities were observed concerning the course of pregnancies of partners. In conclusion, sexual dysfunction and infertility are common long-lasting sequelae in testicular cancer survivors affecting approximately 20% of patients. The relative risk for infertility appeared to be elevated for patients treated with the combination of CT+SRRTM. Twenty-one of 40 patients were able to fulfil their wish for children, and no congenital abnormalities were observed in these children.
