Extragonadal germ cell tumor coexisted with renal cell carcinoma--a case report

A patient was 31-year-old man with the chief complaint of 38 degrees C fever. He was pointed out left renal tumor by abdominal ultrasonography and computerized tomography (CT). CT revealed left infraclavicular, mediastinal and retroperitoneal lymph nodes swelling and left renal tumor. Serum alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (HCG-beta) level were elevated. The diagnosis of extragonadal germ cell tumor and left renal cell carcinoma was confirmed pathologically by infraclavicular lymph node and renal biopsy. He was treated with 4 courses of BEP regimen and interferon-alpha, cimetidine therapy for 2 weeks preoperatively. After serum tumor markers were normal level, he underwent left radical nephrectomy and left infraclavicular, mediastinal and retroperitoneal lymph node dissection. The histology of all lymph nodes was necrotic tissue, but operation was incomplete. Therefore VIP therapy was performed postoperatively. This is the first case of extragonadal germ cell tumor coexisted with renal cell carcinoma in the world.     

Renal autotransplantation in a patient with acute renal infarction following surgery for a dissecting aneurysm

A 58-year-old woman experienced a sudden onset of severe chest and back pain and thus visited our center in October 1999. Contrast-enhanced computed tomography (CT) revealed a Stanford type A acute aortic dissection. The CT also demonstrated a 50 mm ascending aorta and dissection from the ascending aorta via the abdominal aorta to the level of the left renal artery. The perioperative transesophageal echocardiogram showed an intimal tear in the ascending aorta without valvular abnormality. Therefore, we performed graft replacement of the ascending aorta. On the first postoperative day, she developed oliguria and showed a sudden rise in serum creatinine (Cr) and blood urea nitrogen (BUN) levels, necessitating hemodialysis. She required daily hemodialysis or hemofiltration for twenty days. Thereafter, renal function recovered and dialysis was no longer performed. However, on postoperative day 26, the patient complained of sudden lumber pain. Unheralded oliguria was associated with worsening renal function. A CT scan at this point revealed infarction of the left kidney. During surgery, the left kidney was excised for heterotopic autotransplantation. Extensive thrombosis within a true lumen of the left renal artery was revealed. Following removal of the thrombus and perfusion with heparinized cold saline, renal autotransplantation to a heterotopic site in the pelvis were performed. Although the patient required hemodialysis for five days, renal function recovered gradually. She was discharged five months later. In our experience, it appears that heterotopic renal autotransplantation by which normal arterial perfusion distal to the dissection is reestablished is a good therapeutic option for reperfusion of the ischemic kidney compromised by a progressive dissection of the thoracoabdominal aorta.     

Adjunctive nephrectomy at post-chemotherapy retroperitoneal lymph node dissection for nonseminomatous germ cell testicular cancer

PURPOSE: Patients with metastatic testicular cancer with residual masses encasing the renal hilum or kidney after platin based chemotherapy may require adjunctive nephrectomy to achieve complete resection at post-chemotherapy retroperitoneal lymph node dissection. We reviewed our experience with adjunctive nephrectomy to assess the impact on cancer control and renal function. MATERIALS AND METHODS: Of 647 post-chemotherapy retroperitoneal lymph node dissection procedures performed at our institution since 1989 adjunctive nephrectomy has been performed in 32 patients (5%). Patient information was obtained from a prospective database. Median followup was 31 months. RESULTS: Of the adjunctive nephrectomy procedures 17 (53%) were performed in high risk settings such as post-salvage chemotherapy, desperation retroperitoneal lymph node dissection, late relapse and reoperative retroperitoneal lymph node dissection. Disease was present in the adjunctive nephrectomy specimen in 21 patients (66%). Following post-chemotherapy retroperitoneal lymph node dissection 7 patients had disease relapse and 5-year disease-free survival was 66%. No case of relapse required substitution for cisplatin due to compromised renal function. Progression to chronic renal insufficiency occurred in 3 patients, 1 of whom required hemodialysis. The calculated creatinine clearance after adjunctive nephrectomy was more than 30% below the age specific norm in 14 patients (50%) and median patient age was 40 years. CONCLUSIONS: Adjunctive nephrectomy at post-chemotherapy retroperitoneal lymph node dissection is most frequently performed in patients with high risk features to ensure the completeness of resection. When indicated, adjunctive nephrectomy should be performed because residual cancer is frequently present and long-term cancer control can be achieved in 66% of patients. Although adjunctive nephrectomy did not interfere with subsequent chemotherapy, the renal reserve in these patients was substantially reduced in 50%, emphasizing the importance of preventative measures to preserve long-term renal function.     

Laparoscopic Retroperitoneal Lymph Node Dissection for Nonseminomatous Germ Cell Tumors: Indications and Limitations

Purpose

We describe our experience with laparoscopic retroperitoneal lymph node dissection in 26 patients with nonseminomatous germ cell tumors: 17 had stage I disease with no clinical (computerized tomography, ultrasound or tumor markers) evidence of metastases and 9 (2 with stage IIb and 7 with stage IIc disease) had residual tumor after chemotherapy but with negative tumor markers. Laparoscopic dissection was performed to assess more fully pathological status of the relevant retroperitoneal lymph nodes in both groups.

Materials and Methods

The patient was positioned and trocars were introduced at sites similar to that used for transperitoneal laparoscopic nephrectomy (flank position with 3, 10 mm. and 2, 5 mm. ports). After the white line of Toldt was incised and the colon was reflected anteromedially, the retroperitoneal space was exposed. The landmarks of lymph node dissection were then isolated, including the ureter, aorta, inferior vena cava and both renal veins. Lymph node dissection was performed identical to that for open surgery, with a modified template including the paracaval, interaortocaval, upper preaortic and right common iliac nodes for right tumors, and para-aortic and upper preaortic nodes for left tumors. Lymph node chains were retrieved with a small organ bag.

Results

The procedure was completed successfully in 16 of 17 patients with stage I disease (mean duration 268 minutes for the left and 312 minutes for the right sides). No intraoperative complications were encountered. One patient had delayed ureteral stenosis requiring operative repair, 1 had a pulmonary embolism with an uneventful outcome and 1 who underwent laparoscopic retroperitoneal lymph node dissection on the right side later had retrograde ejaculation. Embryonal carcinoma was found in 1 of the 17 patients.Average postoperative hospital stay was 4.5 days for patients without complications or conversion to an open procedure. After a median followup of 27 months no patient had regional relapse but 2 had pulmonary metastases that were treated successfully with 3 cycles of platinum based chemotherapy. Laparoscopic dissection was significantly more difficult in patients with stage II tumors after chemotherapy. Only in 2 patients with stage IIb disease was laparoscopic lymphadenectomy successful. In 5 of the 7 patients with stage IIc cancer portions of the dissection had to be done after conversion to an open (conventional) operation via a small incision (suprainguinal or pararectal). In 1 patient the laparoscopic approach was completely abandoned and converted to an open operation via a standard midline incision. In all 9 cases histopathological examination revealed complete necrosis. No patient has evidence of disease.

Conclusions

Our preliminary experience suggests that a modified laparoscopic retroperitoneal lymph node dissection is feasible for stage I tumors. However, it cannot be recommended after previous chemotherapy (stages IIb and IIc disease).     

Combined resection of the aorta for an esophageal carcinoma invading the aorta through a right transthoracic approach.

The prognosis of esophageal carcinoma invading the thoracic aorta has been extremely poor, as it has been either not resected or only palliatively resected. In recent years a remarkable improvement in survival has been achieved in advanced esophageal carcinoma through an aggressive dissection of the upper mediastinal lymph nodes. This implied that resection only of the aorta without lymph node dissection in these patients was not adequate for curability. Although a resection of the aorta would seem to be performed more easily through a left thoracotomy than through a right thoracotomy, the upper mediastinal lymph node dissection was unsatisfactory through a left thoracotomy. Therefore, we performed combined resection of the aorta using a temporary aorta-aorta bypass together with upper mediastinal lymph node dissection through a right thoracotomy for four patients with the esophageal carcinoma invading the thoracic aorta. This operative procedure was performed safely, and had the advantage that full observation on the extent of the carcinoma was attained together with subsequent radical lymph node dissection in the same field through only the right thoracic approach. This operation may provide a possibility for cure to patients with an esophageal carcinoma invading the aorta, who would otherwise receive only palliative treatment.

Bronchioloalveolar carcinoma illustrating difficulties in diagnosis and determination of operative management; report of a case

A 56-year-old male was admitted to our hospital to treat for an abnormal lung shadow. Computed tomography (CT) revealed the shadow with ground-glass opacity that was 30 mm in diameter at left S6 lesion. Although transbronchial lung biopsy had been performed, histological diagnosis could not be made. We had expected the tumor could not be resected completely with a partial lung resection. Additionally, he refused being done a lower lobectomy without a histological diagnosis. So we performed a S6+S* segmentectomy with No. 7-12 lymph node dissection. Although the intraoperative frozen section diagnosis was an atypical adenomatous hyperplasia, the tumor was finally diagnosed as bronchioloalveolar carcinoma (BAC) because of its nuclear atypia. We did not resect the residual part of left lower lobe because he refused the additional operation and might have histopathologically no residual tumor and lymph node metastasis. At present, he is alive without any evidence of recurrence.     

A case of small cell carcinoma of the renal pelvis

A 77-year-old man visited our hospital with a chief complaint of asymptomatic gross hematuria. He was diagnosed with right renal pelvic tumor (7 cm) involving right renal hilar and inter-aortocaval lymph node metastases by radiological evaluation, and cytologic examination of urine indicated small cell carcinoma. After neoadjuvant chemotherapy with gemcitabine and cisplatin, right nephroureterctomy with bladder cuff, and right renal hilar and inter-aortocaval lymph node dissection was performed. Histological examination of the specimen revealed a small cell carcinoma of the renal pelvis (ypT3N2). After the operation, adjuvant chemotherapy with etopside and carboplatin was administered in combination with radiation therapy. At 5 months after the operation, there has been no evidence of recurrence. To our knowledge, this is the 38th report of a small cell carcinoma originating from the kidney in the literature.     

Improved treatment of thoracic esophageal cancer based on a retrospective study of recurrence following resection

Recurrence after resection of thoracic esophageal cancer was classified according to site of recurrence into 5 categories; 1) local recurrence, 2) recurrence at the anastomotic site, 3) recurrence in cervical or mediastinal lymph nodes, 4) recurrence in abdominal lymph nodes and 5) distant organ metastasis. Although the combined resection of the trachea or aorta was performed in several cases with local extension, its clinical results were not superior to those from palliative resection. To prevent recurrence at the anastomotic site, we performed either pharyngeal anastomosis with laryngectomy or esophageal anastomosis just below the larynx. However, such anastomosis just below the larynx was liable to cause aspiration pneumonia. To prevent lymph node recurrence in the neck or mediastinum, we performed cervical and mediastinal lymph node dissection. However, lymph node recurrence in the upper mediastinum of the left side was occasionally observed in case receiving this operation, with lymph node recurrence being decreased by postoperative irradiation, though prognosis was not always improved. Anti-cancer agents CDDP and VDS or 5Fu were effective. To prevent abdominal lymph node recurrence, we recommend that abdominal lymph node dissection is necessarily performed as for cardiac cancer. To prevent distant organ metastasis, we recommend anti-cancer therapy following radical lymph node dissection.     

Adrenal metastasis of lung adenocarcinoma with unusual sites of lymph node metastasis and concomitant renal cell carcinoma: a case report

A 58-year-old male presented to a clinic with general weakness. Right adrenal tumor was found by computed tomography and he was referred to our hospital. Imaging studies revealed right adrenal tumor (8 cm) with marked swelling of surrounding lymph nodes and synchronous left renal tumor (2 cm) that was weakly enhanced by contrast media. Needle biopsy of the left kidney proved to be clear cell type renal cell carcinoma (RCC) and the preoperative diagnosis was left RCC and right primary adrenal cancer with lymph node metastasis. We performed right adrenalectomy, lymph node dissection and left radical nephrectomy. Pathological findings of right adrenal tumor and lymph nodes were both metastatic adenocarcinoma, which was not consistent with RCC or adrenal-derived carcinoma. Then, we extensively reviewed preoperative radiological examinations and found a small lesion in the left upper lung. This lesion was attached to the mediastinal shadow and there was no obvious lymph node swelling around this lesion. According to pathological findings and an elevation of carcinoembryogenic antigen, the adrenal lesion was diagnosed as adrenal metastasis of lung adenocarcinoma.     

Autologus groin lymph node transfer for “sentinel lymph network” reconstruction after head-and-neck cancer resection and neck lymph node dissection: a case report

Local or distant metastatic recurrence after therapy is observed in 20–30% of cases of head-and-neck cancer. An unfavorable course may occur after cervical lymph node dissection due to loss of immunoprotective lymph nodes in the head-and-neck region. To overcome this problem, we performed autologous lymph node transplantation from the groin after head-and-neck cancer resection and cervical lymph node dissection. The patient was a 63-year-old man with squamous cell carcinoma in the mesopharyngeal lateral wall. After tumor resection and right cervical lymph node dissection, a lymph node-containing superficial circumflex iliac artery perforator flap was transplanted from the left groin. Pathological examination showed that cancer had invaded the primary tumor tissue stump. Thus, radiotherapy (66 Gy) was performed for the residual tumor from days 28 to 84 after surgery. At 12 months after surgery, no recurrent lesion or has developed. The biopsy of flap and lymphatic vessel endothelial hyaluronan receptor-1 (LYVE1) immunostaining shows creditable lymph network in the flap, compared with normal free flap. This case suggests that autologous lymph node transplantation may keep watch on cancer recurrence by reconstruction of the lymph node system in the resected region, and we suggest that this approach may be very useful in cancer therapy.     

Method of radical transabdominal tumor nephrectomy with facultative or systemic lymph node dissection and results in 381 patients

The prognosis of 381 patients without metastases operated on renal cell carcinoma depends on the extent of the lymph node dissection. After facultative lymph node dissection (FLD) the uncorrected actuarial survival rates (SR) are 64 +/- 8% after 3 years and 50 +/- 9% after 5 years compared to 77 +/- 7% (3 years) and 60 +/- 11% (5 years) when systematic lymph node dissection (SLD) was performed. For stage I the better results in the SLD-group (80 +/- 10% 5 years SR for SLD; 67 +/- 13% 5 years SR for FLD) are partially to be explained as a staging-effect, whereas in stage II the difference (92 +/- 10% 5 years SR for SLD; 45 +/- 25% 5 years SR for FLD) is due to the higher radicality of the systematic dissection. In stage III (35 +/- 14% 5 years SR for SLD; 37 +/- 12% 5 years SR for FLD) the predominant influence of the tumor invasion in renal veins cannot be influenced by local extension of the operation. The incidence of lymph node metastases was 16% (n = 170) in the FLD and 23% (n = 211) in the SLD group. When only facultative dissection is done, 30% of lymph node metastases escape detection. Without any lymph node dissection the number of unrecognized lymphmetastases can be expected to be still higher. The controversies about the role of lymph node dissection in radical tumor nephrectomy are mainly caused by the lack of standardized criteria for operative and patho-histological staging procedures. Any conclusions drawn from comparing reports in the literature should be related to these modalities.     

Survival benefits of and indications for extended surgery for advanced gastric cancer]

The surgical management of locally advanced gastric cancer remains controversial. It is also unclear whether the postoperative survival rate could be improved by extended lymph node dissection. The aim of this paper is to determine the survival benefit of and the indications for extended surgery. Lymph node metastasis in the paraaortic area frequently occurs in locally advanced cardiac cancer. In our previous studies, the paraaortic lymph nodes above and below the left renal vein were confirmed to be the terminal destination of lymphatic flow in the upper abdominal cavity. Paraaortic lymph node dissection is essential for curarive resection in some cases of advanced gastric cancer. The 5-year survival rate in patients who undergo paraaortic lymph node dissection is nearly 15% according to the literature. Patients with metastasis of the paraaortic lymph nodes on only one side and with fewer than four involved nodes clearly benefit from paraaortic lymph node dissection. It is indicated in cases with metastasis or suspected metastasis of the left or right cardiac lymph node or N2 lymph node station. There is little survival benefit from combined resection of involved organs (T4 disease) and it should only be performed in a select group of patients. Extended surgery for locally advanced gastric cancer, however, is feasible and has acceptable operative morbidity and mortality rates.     

Effect of extended paraaortic lymph node dissection on postoperative pancreatic function in gynecologic procedures

BACKGROUND: We tested a hypothesis that extended gynecological paraaortic lymph node dissection seriously impairs postoperative pancreatic function. METHODS: We studied 82 patients who underwent gynecologic surgery for malignancy from January, 2002 to October, 2003. After scheduled operation, we assigned them to one of two groups; patients who underwent extended gynecological paraaortic lymph node dissection (n=34) or those who did not (n=48). We measured plasma amylase levels in all patients before operation and 1, 3, 7 days after operation. RESULTS: Preoperative amylase levels were the same in the two groups. Time-dependent increases in plasma amylase level were noted in both groups. From 1 to 3 days after operation, however, plasma amylase levels were significantly higher in patients who had undergone paraaortic lymph node dissection than in those who had not. Furthermore, lethal postoperative pancreatitis developed in one patient who showed marked high levels in plasma amylase level after paraaortic lymph node dissection. CONCLUSIONS: Our results suggest that paraaortic lymph node dissection in gynecologic operations seriously impairs pancreatic function and that one should maintain a high suspicion of postoperative pancreatitis.     

The indication for lymph node dissection around abdominal aorta in gastric cancer

In 77 cases with gastric cancer, for which lymph node dissection around the left renal vein was performed in the past 5 years, the sites and routes of metastasis were investigated to determine the indication for dissection around the left renal vein. The rate of metastasis to the lymph nodes around the left renal vein was 23.4%. The typical routes of metastasis were 1) the left lower phrenic route, 2) via the splenic artery, 3) via the celiac artery, 4) via the superior mesenteric artery and 5) the postpancreatic route. Dissection was considered to be indicated for the patient with N2 or more distant lymph node involvement and for cases with carcinoma of the upper part of the stomach or whole stomach with N2 positive lymph node. It was also indicated for N3(+) cases or No. 9(+) cases of carcinoma of the middle and lower parts of the stomach. Needless to say the absence of other non curative factors is required.

Spontaneous dissection of renal artery: long-term results of extracorporeal reconstruction and autotransplantation1

PURPOSE: We undertook this study to assess the outcome of spontaneous dissection of the renal artery and its branches surgically treated with extracorporeal reconstruction and autotransplantation. SUBJECTS: Between 1975 and 1996, 15 consecutive patients (19 kidneys) with spontaneous renal artery dissection underwent renal artery reconstruction. Fourteen patients had accelerated hypertension. Five patients had impaired renal function. In 14 patients the dissection was associated with fibrodysplasia, and in 1 patient it was related to arteriosclerosis. INTERVENTION: In 17 kidneys extracorporeal reconstruction and autotransplantation was used. The renal artery of 1 kidney was reconstructed in situ. One primary nephrectomy was performed. RESULTS: There were no operative deaths or major morbidity. All but 1 reconstruction was successful (94.4%). Results at follow-up (range, 1-8 years) were favorable in 14 patients; 79% had satisfactory blood pressure control, and all patients had normal renal function, including those with impaired renal function preoperatively. CONCLUSIONS: Extracorporeal reconstruction and autotransplantation can be effectively used in patients with spontaneous renal artery dissection located in or extending into the distal branches. Early recognition and appreciation of the clinical presentation of spontaneous renal artery dissection are important.     

达芬奇机器人甲状腺手术中甲状旁腺的损伤因素及保护

目的分析达芬奇机器人甲状腺手术中甲状旁腺损伤的相关因素,探讨甲状旁腺保护的方法,避免永久性甲状旁腺功能减退的发生。 方法回顾性分析2014年1月至2016年5月在济南军区总医院甲状腺乳腺外科行达芬奇机器人甲状腺手术的190例患者的临床资料,统计术后患者出现低甲状旁腺激素(PTH)及低血钙的发生率,分析术后发生甲状旁腺功能减退的相关因素,探讨术中如何保护甲状旁腺及其功能。 结果患者术后暂时性低PTH的发生率为20.53%(39/190),暂时性低血钙的发生率为23.68%(45/190),术后随访无永久性甲状旁腺功能减退发生。甲状腺全切术后低PTH、低血钙的发生率高于腺叶 ＋ 峡部切除术者(χ²＝14.789,11.604;P＝0.000,0.001)。行中央区淋巴结清扫的患者术后低PTH、低血钙的发生率高于未清扫者(χ²＝11.200,17.771;P＝0.001,0.000)。甲状旁腺原位保留者术后低PTH、低血钙的发生率低于切除后自体移植者(χ²＝5.536,4.851,6.140,5.453;P＝0.019,0.028,0.013,0.020)。 结论在达芬奇机器人甲状腺手术中,甲状腺全切除、中央区淋巴结清扫、甲状旁腺切除后自体移植是造成患者术后暂时性甲状旁腺功能减退的重要影响因素。在达芬奇机器人手术系统下,准确识别甲状旁腺,精细化手术操作,原位保护甲状旁腺及血供,是预防永久性甲状旁腺功能减退的有效方法。     

Angiomyolipoma with regional lymph node involvement: a case report and literature review

A 28-year-old man without tuberous sclerosis, who complained of pollakisuria, consulted to our hospital for a left renal mass. Abdominal computed tomography revealed a solid mass without a lipid component, 10 cm in diameter, in the left kidney and with regional lymphadenopathy. Renal arteriography showed a hypervascular mass, demonstrating multiple tumor stains and aneurysms. Left radical nephrectomy and perihilar lymph node dissection were performed for an anticipated diagnosis of malignant tumor in November 2001. The histopathological diagnosis was an angiomyolipoma with lymph node involvement. Immunostaining for myogen markers was positive in the renal mass and lymph node tumors. He was free from disease ten months after surgery.
