[Laparoscopically extended hysterectomy for cervix cancer: technique, indications and results. Apropos of a series of 41 cases in Clermont].

We report a study of 41 radical hysterectomies performed through laparoscopic approach for carcinoma of the cervix uteri. According to the FIGO staging, the tumors were classified as 12 stages Ia2, 24 stages Ib, 4 stages IIa and 1 stage IIb. 17 patients were treated by exclusive surgical procedure. 24 patients received a combination of radiation therapy and surgery 2 patients had a tumor of the cervical stump after subtotal hysterectomy. The mean duration of the procedure was 270 minutes. The post-op stay was 6.5 days. There was no major operative and postoperative complication. Only one patient required a blood transfusion. The intravenous pyelogram control was correct in all cases. At this time, with a 4 to 76 months follow-up, no recurrence was observed. This experience suggests the faisability of the laparoscopic radical hysterectomy. This approach seems to be convenient in young and non obese women with a tumor less than 4 cm in the greatest diameter.

[Peritoneal tuberculosis. Value of laparoscopy].

We report 6 cases of tuberculous peritonitis, focusing on the contribution of laparoscopic exploration. The initial diagnosis was erroneus in all cases: the polymorphous clinical presentations suggested another infectious disease or cancer disease. Laparoscopy was performed in 5 patients who had ascitis and in 1 with plastic peritonitis. At laparoscopy, the peritoneum showed miliary granulations and inflammatory adherences on the visceral or parietal sheats. Bacteriological analyses of the ascitic fluid were positive in only one case. The diagnosis was confirmed after culture of biopsy specimens and identification of the Kock bacilli or on the basis of objective evidence of an epithelioid giant-cell granuloma with caseous necrosis. Outcome was favorable after appropriate antibiotic therapy.

[Metastatic epiduritis with invasiveness of the left renal vein].

We report a case of epidural metastasis with left renal vein invasion. This nonsymptomatic venous involvement was detected by ultrasonography and confirmed at CT and MR imaging. Such an unusual cause of renal vein tumor thrombus occurred through a lumbar vein which represents one of its usual collateral branches.

[Search for genetic risk in surgical indications in oncology].

We report the case of 68-year-old woman with an adenocarcinoma of the right colon. The family history also suggested that she might also be at risk of ovarian or endometrial cancer. Thus despite the lack of gynecologic symptoms, abdominal hysterectomy and bilateral salpingo-oophorectomy was proposed at the time of the right colectomy endometrial carcinoma was discovered at surgery. This finding and the family pedigree were consistent with the diagnosis of familial Lynch II syndrome. Appropriate biomolecular analyses were undertaken. This case shows the importance of family history taking in patients with cancer. The surgeon should be aware of such situations and correlate indications and procedures with the genetic risk of the patients.

Technetium-99m-sestamibi uptake in breast tumor and associated lymph nodes.

UNLABELLED: The aim of this study was to measure the accumulation of 99mTc-sestamibi in breast tumors and their axillary lymph nodes in patients undergoing scintimammography. METHODS: Eighteen patients who were scheduled for breast surgery underwent scintimammography with 740 MBq of 99mTc-sestamibi on the day before the operation. The next morning, reinjection with 370 MBq was performed. Immediately after the surgical procedure, the 99mTc activity of the tumor samples and, when available, the related lymph nodes was measured in a gamma counter. The samples were weighed and prepared for histological analysis. The activity of each sample was normalized to the mean activity of normal tissue samples obtained from the same patient. RESULTS: Among the 198 samples analyzed, the relative uptake of sestamibi was increased in 111 containing normal lymph nodes (1.80+/-0.79 vs 1.00+/-0.22, p<0.05), as well as in the seven containing invaded lymph nodes (2.01+/-0.83, p<0.01) and more dramatically, in the 22 with a carcinoma (5.64+/-3.06, p<0.001). In two patients with a benign lesion, both scintigraphy and counting demonstrated increased activity in the tumor. Four patients had negative scan results despite the presence of malignant tumor and a more than fourfold increase of sestamibi concentration in two of them. CONCLUSION: Technetium-99m-sestamibi concentrates strongly in breast carcinoma, sometimes even when the scan results appear normal, and mildly in lymph nodes, especially when invaded; it also concentrates in some benign tumors, possibly in relation to the presence of epithelial hyperplasia.

[Axillary lymph node dissection in clinically occult breast cancer].

The study concerns 265 patients with axillary lymph node dissection for non-palpable breast cancer. The mammographically detected breast tumors were: 36 ductal carcinomas in situ (DCIS), 23 microinvasive carcinomas, 206 invasive carcinomas of which 179 were invasive ductal cancers (IDC), 25 invasive lobular cancers (ILC) and 2 mucinous invasive carcinomas. The histologic size of the invasive component was < or = 5 mm in 38 cases, 6-10 mm in 84 cases, 11-15 mm in 53 cases, 16-20 mm in 16 cases, > 20 mm in 15 cases. Axillary dissection was performed immediately during the initial surgical procedure in 209 patients (79%) or secondarily in 56 (21%) according to the results of intraoperative examination of surgical specimens on frozen sections. Axillary lymph node involvement was not found in DCIS, microinvasive carcinomas or invasive carcinomas < or = 5 mm in size. Among all 206 invasive breast carcinomas, lymph node involvement was found in 7.8% (16/206) of cases. There were 9/84 (10.7%) in tumors > 10 mm, 7/122 (5.8%) in tumors < or = 10 mm. Thus, it is concluded that lymph node involvement is unlikely to be found in patients with non palpable breast cancers, specially those with carcinoma in situ, microinvasive breast tumors and invasive breast cancer with less than 5 mm maximum diameter size. Axillary dissection may be avoided in these patients. However, the use of new prognostic factors of lymph node involvement may help in the definition of patient group.

[Mastectomy with immediate reconstruction for invasive breast cancer. Comments on indications and technique. A series of 112 cases].

A series of 112 mastectomies with immediate breast reconstruction performed in women with invasive cancer of the breast were followed for a mean of 30 months to determine cancer outcome, morbidity and aesthetic results of the different surgical techniques. The patients were divided into 3 groups according to indications: 49 cases with local recurrence after conservative treatment; 37 cases of large or multifocal tumours operated after chemotherapy and radiotherapy; 26 cases after tentative conservative surgery with incomplete tumourectomy. A total of 98 patients (87.5%) were irradiated before mastectomy with immediate breast reconstruction. Twenty-eight simple implants, 50 musculocutaneous flaps using the latissimus dorsi with implant and 34 musculocutaneous flaps with the rectus abdominis. During follow-up 16 patients died and cancer relapsed in 13 surviving patients. Seven local recurrences were observed. In all cases of early relapse, which may have possibly been triggered by immediate breast reconstruction, the patients had very poor prognosis criteria. Surgery took longer for mastectomy with immediate breast reconstruction using the rectus abdominis flap and required transfusion in 88% of the cases. Combining all the techniques, 19% of the patients had postoperative complications and 25% late sequellae. The aesthetic results were considered as good immediately after surgery in 14% of the patients with a simple implant, in 45% of those with a latissimus dorsi flap and in 81% of those with a rectus abdominis flap. Second surgical procedures to improve the aspect were performed in half the patients with a simple implant giving 50% good results, in 40% of the patients with a latissimus dorsi flap giving 68% good results and in 12% of the patients with a rectus abdominis flap giving 84% good results. In this series, patient satisfaction was closely related to the aesthetic quality of the results. Integrated into a well-planned multidisciplinary protocol, mastectomy with immediate breast reconstruction does not appear to affect the cancer outcome. Immediate breast reconstruction is a complex procedure and requires experience in plastic surgery to reduce the number of complications and to improve aesthetic results. Reconstruction with a rectus abdominus flap appears as the superior technique.

[Epithelioma of the penis treated with surgery. Study Group on Urogenital Tumors of the National Federation of the Centers for Cancer Control].

OBJECTIVES: To evaluate the efficacy and morbidity of surgical treatment of carcinoma of the penis. This series of patients was derived from a retrospective multicentre study (1959-1989), initially concerning 506 patients, all treatments combined. METHODS: One hundred and sixty-eight patients treated by surgery or surgery followed by external radiotherapy between 1959 to 1989 were included. The mean follow-up is 14.4 years and the mean participation is 4.7 years. Total or partial amputation was performed as first-line treatment in 89 patients (53%) and as second-line treatment in 11 patients (7%). Thirty-two patients received external radiotherapy as a complement to surgery. Inguinal lymph node dissection was performed as first-line treatment in 68 patients (41%) and secondarily in 19 patients (11%). Postoperative inguinal radiotherapy was performed in 52 patients. Monofactorial statistical analysis of prognostic factors is proposed. RESULTS: The 5-year local control rate was 84%; it was independent of the stage of the tumour; the survival of the patients dying from any cause was 53%, the progression-free survival was 69% and the survival of patients dying from cancer of the penis was 75%. The vital prognosis is statistically significant related to the lymph node status. No significant relationship was observed between lymph node status and tumour stage. 61 complications involving the penis were observed in 40 patients (24%). Thirty-seven patients developed complications secondary to the lymph node dissection (24 cases of oedema of the lower limbs and 13 cases of inguinal sclerosis). CONCLUSION: Surgical treatment ensured a local control globally comparable to that obtained with brachytherapy, but unlike this technique, the local control is independent of the stage. Brachytherapy should not always be performed in favour of mutilation for advanced tumours because the iatrogenic effects of brachytherapy are increased in these cases. An approach to the treatment of lymph nodes is proposed based on the authors' experience and the data of the literature.

[Expansive uterine myoma during tamoxifen therapy. 11 cases].

Tamoxifen, a non-steroid anti-oestrogen derivative of diethylstilboestrol, is the main drug used for hormone therapy for hormone-dependent breast cancer. This ambivalent drug has both antagonist and agonist effects. While tamoxifen blocks tumour growth it can also have an undesirable agonist effect on the genital tract. The uterus is a target organ for this paradoxical action due to proestrogenic stimulation of the endometrium and the myometrium. We observed eleven cases of uterine fibromyoma during treatment with tamoxifen which required hysterectomy due to increased tumour volume. The pathology report on the surgical specimens did not show any evidence of malignancy. Differential diagnosis is based on sarcomatous degeneration of the fibromyoma and presence of intra-myomatous metastases from the breast. Hysterectomy is indicated in menopaused patients with a symptomatic fibromyomatous uterus before starting long-term anti-oestrogen therapy for hormone-dependent breast cancer.

[Stewart-Treves syndrome. Immunohistochemical study apropos of 2 cases].

Two women (63 and 68 years) presented with primary angiosarcomas of the skin which had developed on an area of chronic lymphoedema after radiosurgical treatment for breast cancer 4 and 13 years earlier. Immunohistochemistry tests formally eliminated epithelial metastasis and produced evidence in favour of lymphatic or capillary vascular proliferation. Endothelial affinity for anti-factor VIII and positive tests for certain markers of intermediary filaments (actin, vimentin) confirmed the vascular and conjunctive tissue origin of the tumours.

Laparoscopic staging of early ovarian cancer.

The relevance of staging in early ovarian carcinoma is reviewed in light of the advances in surgical laparoscopy. Data from the literature suggest that a lymphadenectomy should be performed instead of a sampling. We have realized the former through laparoscopy. In this paper we propose a detailed surgical technique, similar to the laparotomy approach, that ensures an adequate nodal evaluation. Ten patients underwent a completion of staging by laparoscopy, including peritoneal washings for cytology, peritoneal and ovarian biopsies, an infracolic omentectomy, and a lymph node dissection. The use of laparoscopy for staging of early ovarian carcinoma appears to be a valuable alternative to traditional surgical staging.

[Post-laparoscopic incisional hernia. Apropos of a case].

Incisional hernia occurred in a patient after laparoscopic hysterectomy. The greater omentum was incarcerated in the tract of the suprapubic trocar (12 mm diameter). Diagnosis and treatment were performed during a second laparoscopy procedure. The greater number of trocar instruments and their larger diameter increases the risk of parietal morbidity after laparoscopic procedures. Elective closures of trocar incisions is recommended when exceeding 10 mm. Prevention of extra-umbilical incisional hernias and dehiscences appears to be more effective when suture is performed under laparoscopic vision with the trocar inserted. Both the aponevrosis and the peritoneal membrane should be treated.

[Rare tumors of the cervix: three case reports: rhabdomyosarcoma, granulocytic sarcoma and lymphoma].

Three rare cases of tumours of the cervix are reported: embryonal rhabdomyosarcoma, granulocyte sarcoma and lymphoma. There were particular problems with diagnosis in each case requiring histochemistry, immunohistochemistry and ultrastructure examinations. Embryonal rhabdomyosarcoma is a uncommon tumour in the adult. Clinically, there is a vegetative formation but no botryoid aspect. Striated muscle cell proliferation, suggested by the morphology of the malignant cells was confirmed by immunohistochemistry which demonstrated desmine and vimentine and by the ultrastructural study which demonstrated Z lines in the cytoplasm of the malignant cells. Granulocyte sarcoma is characterized by a non-tumoural non-destructive infiltration of inflammatory-like cells. Their granulocyte nature is confirmed by histochemistry, the Leder's reaction on frozen samples, immunohistochemistry (expression of NP57). Electron microscopy can also be used. The diagnosis of lymphoma is difficult due to the non-tumoural nature of the lymphomatous infiltration which can simulate inflammatory reaction. In our case, the diagnosis was made on the tumoural aspect of the biopsy made in the deep infiltration zone of an adjacent organ (bladder). Immunohistochemistry demonstrated the lymphoid nature of the tumour and identified a B phenotype. The ultrastructural study gave little information.

[Preoperative localization of parathyroid adenomas. Role of cervical ultrasonography].

OBJECTIVES: We evaluated the sensitivity and specificity of cervical ultrasonography for the detection of primary parathyroid adenomas. METHODS: From January 1990 to May 1992, ultrasonography was performed before exploratory cervicotomy in 30 patients (10 males, 20 females, mean age 56.3 yr) whose diagnosis was primary hyperparathyroidism based on radioimmunoassay of parathyroid hormone. The same trained operator performed all the ultrasonographic examinations. RESULTS: Twenty-six parathyroid tumours were detected in 23 of the 30 patients examined by ultrasonography. The four standard localizations and one ectopic tumour were visualized. At surgery 37 tumours were found in 30 patients. Among the 11 false negatives, the operator had identified an abnormal tumour incorrectly as a cervical lymph node in 2. Most of the false negatives occurred early in the study. The sensitivity of ultrasonography was thus 70 % with a 100% specificity. CONCLUSIONS: Cervical ultrasonography is a reliable, non-invasive and relatively inexpensive examination which should be used as a first-line test for the aetiological assessment of hyperparathyroidism.

[Postmenopausal hydrometra. Influence of tamoxifen].

Vaginal ultrasonography of the uterus using a high frequency endocavitary probe was performed in 300 postmenopausal women: 150 receiving no replacement nor suppressive hormone therapy and 150 receiving adjuvant anti-estrogen treatment in the form of tamoxifen because of breast cancer. Evidence was found of hydrometra in 84 cases (28%): 10 in the group taking no hormone therapy (6.6%) as compared with 74 in the group exposed to tamoxifen (49.3%). The difference was statistically significant (p < 0.01). In addition, mean thickness of the endometrium was estimated at 6 mm (range: 2-40) in the first group versus 12 mm (range: 3-60) in the second (p < 0.001). It emerged from this comparative ultrasound study that the incidence of postmenopausal hydrometra was influenced by taking tamoxifen. Fluid secretion appearances seen one out of two in treated patients reflect the paradoxical proestrogenic type action of tamoxifen on the uterine mucosa.

[Clinically occult invasive cancers of the breast. Apropos of 136 cases].

Between 1978 and 1991, one hundred and thirty-six surgical excision biopsies were performed in our institution for clinically occult breast cancers. A retrospective analysis of histopathologic characteristics was carried out in order to determine the prognostic factors of these cancers detected by mammography. Mammographic findings consisted of microcalcifications alone (49 cases), microcalcifications with opacity (20 cases), stellate opacity (52 cases) and well-circumscribed opacity (12 cases). Preoperative localization was achieved by mammography in 109 cases and ultrasonography in 27 cases. The size of malignant lesions ranged from 3 to 25 mm, 76 lesions were less than 10 mm in diameter. The histopathologic findings were as follows: invasive ductal cancer (IDC) 113 cases (83%), invasive lobular cancer (ILC) 11 cases (8%), ductal or lobular cancer in situ with microinvasion 12 cases (9%). Breast conserving treatment was performed in 106 cases (78%). A high proportion of well differentiated tumors was encountered-59 grade I (52%) were identified out of 113 IDC-and the incidence of axillary node metastases was less than 10%. Clinically occult breast cancers seem to exhibit favorable prognostic factors.
