Feasibility of Induction Chemotherapy Using Bronchial Arterial Infusion for Locally Advanced Non-Small Cell Lung Cancer: A Pilot Study

Purpose: We examined the feasibility and effectiveness of bronchial arterial infusion (BAI) as induction chemotherapy before surgery for locally advanced non-small cell lung cancer (NSCLC). Methods: Eighteen patients with locally advanced NSCLC were given BAI consisting of cis-diamminedichloroplatinum (CDDP) (50–100 mg/m²) as induction chemotherapy before surgery (induction BAI). Six patients with clinical stage IIIA cancer had bulky N2 metastatic lymph nodes, and 12 patients with clinical stage IIIB cancer had T4 disease. Results: Of the 18 patients, 12 (67%) showed a partial response to the BAI therapy. Standard pulmonary resection was performed in 5 patients, pulmonary resection with the combined resection of adjacent organs was performed in 10 patients, and pulmonary resection with carinal resection and reconstruction was performed in 3 patients. Complete resection was possible in 14 patients (78%). There were no serious BAI therapy-related complications or postoperative deaths. The 5-year survival rate of the 18 patients was 35.7% and the median survival time (MST) was 19.4 months. Survival was better when complete resection was achieved after the induction BAI, especially in patients with stage IIIB (T4) disease. Conclusion: Based on our preliminary findings, BAI with CDDP as induction chemotherapy is feasible and may be an effective therapeutic modality for locally advanced NSCLC.

Carinal resection of bronchogenic carcinoma

Carinal resection was performed in 10 cases of bronchogenic carcinoma during 12 year-period. The mean age of patients was 58 years, with a range of 42 to 68 years. There were 7 male and 3 female. The tumor was located on the right side in 7 cases, on the left side in 1 case on the carina in 2 cases. The histological examination showed squamous cell carcinoma in 5 cases, adenocarcinoma in 4 cases and adenoid cystic carcinoma in 1 case. The staging revealed T3N2 M0 Stage IIIA in 2 cases, T4N0M0 Stage IIIB in 1 case, T4N1M0 Stage IIIB in 1 case, T4N2M0 Stage IIIB in 5 cases and T4N3M0 Stage IIIB in 1 case. The surgical methods were as follows; sleeve pneumonectomy in 5 cases, wedge carinal resection with pulmonary resection in 3 cases (right sleeve upper lobectomy in 2 cases and right pneumonectomy in 1 case), carinal resection in 2 cases. The site of bronchial anastomosis was overlapped by thymus in 6 cases. The 30-day mortality rate in tracheo-carinal resection was 10% (one patient). Eight patients died and remaining 2 patients are still alive without any evidence of recurrence. 5-year survival rate was 36%. These outcomes were almost equal to those of surgical case in the same stage.     

Allergic reaction to CDDP: report of 4 cases

Four cases of CDDP allergic reaction (CDDP reaction) are reported. CDDP was given intravenously with vinka-alkaloid and bleomycin or cyclophosphamide (CDDP combination therapy). Case 1 was a 59-year-old man with left ureteral squamous cell carcinoma. The tumor was so large and infiltrated into the retroperitoneal space, that he had conservatively undergone only left nephrectomy and tumor biopsy. Post-operative CDDP combination therapy was performed. Soon after the beginning of the 6th CDDP drip-infusion, a reaction to CDDP occurred. Case 2 was a 22-year-old man diagnosed to have left testicular embryonal carcinoma with multiple pulmonary metastases. After radical orchiectomy and retroperitoneal lymphadenectomy, CDDP combination therapy was performed. At the beginning of the 8th CDDP drip-infusion, a reaction to CDDP occurred. Case 3 was a 49-year-old man diagnosed to have non-papillary bladder carcinoma. Although his bladder was tumor free by TUR-Bt, distant lymph node metastases occurred. CDDP combination therapy was performed. At the beginning of the 6th CDDP drip-infusion, a reaction to CDDP occurred. Case 4 was a 64 year-old-man diagnosed to have bladder carcinoma which was recurrent from right renal pelvic tumor. After total cystectomy and ileal conduit, CDDP combination therapy was performed for diffuse retroperitoneal lymph nodes metastases. At the beginning of the 8th CDDP drip-infusion, a reaction to CDDP occurred. Reaction to CDDP developed at the 6th to 8th course of combination chemotherapy with CDDP, i.e., 450 to 700 mg of CDDP in total doses.(ABSTRACT TRUNCATED AT 250 WORDS)     

Five-year survival after sleeve pneumonectomy combined with the superior vena cava replacement for lung cancer

The authors report an excellent long-term survival after sleeve pneumonectomy combined with the superior vena cava (SVC) replacement for T4N2M0 non-small cell lung cancer. N2 disease was objectified by mediastinoscopy before an inductive treatment. After three cycles of platinum-paclitaxel combination a partial response was proved. Right pneumonectomy with ePTFE graft replacement of directly invaded SVC was performed. The carinal resection was forced intraoperatively, because of the positive resection margins of the right main bronchus. The direct invasion into SVC, residual N2 disease and definitive free resection margins were confirmed histologically. This patient has survived for 5 years after combined extended lung resection without any relapse; the SVC graft still remains functional.     

Extended operation for lung cancer invading the aortic arch and superior vena cava

Extended operation for lung cancer and mediastinal carcinoma involving the aortic arch or superior vena cava was performed in six patients. In three patients with lung cancer invading the right side of the mediastinum, sleeve pneumonectomy (two patients) or sleeve lobectomy was followed by resection and reconstruction of the superior vena cava with ringed polytetrafluoroethylene grafts. One patient with squamous cell carcinoma and T4 N1 M0 disease was alive and free of disease more than 34 months after the operation. The other patients with adenocarcinoma (T4 N1 M0) and adenosquamous cell carcinoma (T4 N2 M0) died 18 and 5 months after the operation of systemic metastases. In two patients with invasion of lung cancer into the left side of the mediastinum, resection and reconstruction of the aortic arch and left common carotid artery were performed by a femoro-femoral bypass. These patients had adenocarcinoma (T4 N2 M0) and large cell carcinoma (T4 N1 M0) and died of systemic metastases and bleeding during reoperation 12 and 4 months after the initial operation. In one patient with mediastinal squamous cell carcinoma, resection and reconstruction of the aortic arch and left subclavian artery were performed by application of a temporary bypass graft between the ascending and descending aorta. This patient was alive and free of disease more than 17 months after the operation.     

Carinal resection for bronchogenic carcinoma

The purpose of this study was to evaluate the results of carinal resection for bronchogenic carcinoma in our institute. From 1981 to 1999, 24 carinal resection were performed for squamous cell carcinoma (n = 19), adenoid cystic carcinoma (n = 2), small cell carcinoma (n = 1), adenocarcinoma (n = 1), and mucoepidermoid carcinoma (n = 1). Nineteen underwent sleeve pneumonectomy, 2 had carinal resection without lung resection, 2 had carinal resection with right middle and lower lobectomy, and 1 had wedge pneumonectomy. In the patients with sleeve or wedge pneumonectomy, there were 5 operative death and 3 patients had survived for more than 3 years. Two patients with low-grade malignant tumors underwent carinal resection without lung resection and survived more than 10 years. We believe that limited carinal resection for low-grade malignant tumors are safe and valuable procedure. Careful selection of patients with sleeve or wedge pneumonectomy is mandatory.     

Left upper division sleeve segmentectomy for early stage squamous cell carcinoma of the segmental bronchus: report of two cases.

Early hilar lung cancer is rare. It is usually curable if properly diagnosed and treated. We recently encountered two cases of early stage squamous cell carcinoma of the left upper division bronchus, which responded well to left upper division sleeve segmentectomy. Case 1 was a 74-year-old man, a heavy smoker, who was referred to our hospital after sputum cytology had resulted in a positive diagnosis while receiving inpatient care for heart failure at another hospital. Bronchoscopy revealed a thickened tumor at the spur between left B(1+2) and B(3). Squamous cell carcinoma was diagnosed by forceps biopsy via bronchoscopy. Left upper division sleeve segmentectomy with lymph node dissection was performed. Since the bronchi to be anastomosed to each other were greatly different in diameter, telescoped anastomosis was used. His postoperative course was uneventful, and he continues to show good respiratory condition, without any evidence of recurrence 25 months after surgery. Case 2 was a 60-year-old man, a heavy smoker, who was identified by sputum cytology as needing detailed examination during a mass screening of high-risk groups for early detection of lung carcinoma. Bronchoscopy revealed a nodular tumor at the orifice of the left upper division bronchus. Squamous cell carcinoma was diagnosed by forceps biopsy via bronchoscopy. Left upper division sleeve segmentectomy with lymph node dissection was performed. During surgery for this case, the lingular bronchus was dissected obliquely to make its cross-section wide enough to match the diameter of the left upper lobe bronchus to which the former was anastomosed. His postoperative course was uneventful, and he shows good respiratory condition, without any evidence of recurrence five months after surgery. The pathological stage was TisN0M0 (stage 0) in both patients, and their tumors were confirmed as early hilar lung cancer. Sleeve segmentectomy, aimed at radical resection of cancer while preserving lung function, can serve as a standard procedure for surgical treatment of cases of early hilar lung cancer confined to the segmental bronchi.     

Carinal resection and reconstruction for recurrent lung cancer

A patient with a recurrent tumor in the trachea adjacent to the right main bronchus was treated by surgical resection 19 months after undergoing surgery for the primary cancer. The patient had previously undergone right upper lobectomy for T1N0M0 stage I squamous cell carcinoma. A carinal resection was performed which included 4 rings of the trachea, 2 rings of the righ main bronchus, and 1 ring of the left main bronchus. Reconstruction consisted of an end-to-end anastomosis of the trachea and left main bronchus, and an end-to-side anastomosis of the right and left main bronchi. The postoperative course was uneventful, and at present the patient is healthy 12 months following reoperation.     

Bilateral approach for thoracoscopic esophagectomy with lymph node dissection in the dorsal area of the thoracic aorta in patients with esophageal cancer: A report of two cases

IntroductionThe incidence of lymph node metastasis in the dorsal area of the thoracic aorta (DTA) is relatively low in patients with esophageal cancer. It is difficult to approach the DTA using surgical procedures, such as an open thoracotomy and thoracoscopy in the left decubitus position.Case presentationCase 1: A 70-year-old man with esophageal cancer underwent thoracoscopic esophagectomy with mediastinal lymph node dissection via a right thoracoscopic approach, followed by lymphadenectomy in the DTA via left thoracoscopy in the prone position. Microscopic findings revealed two metastatic lymph nodes in the DTA. The definitive diagnosis was squamous cell carcinoma of the esophagus, and the pathological stage was T2N3M0 (Union for International Cancer Control [UICC], 7th edition). The patient showed lung metastasis 8 months after the surgery. Case 2: A 72-year-old man with esophageal cancer underwent esophagectomy via a bilateral approach in the prone position, using a similar procedure as in case 1. The definitive diagnosis was squamous cell carcinoma of the esophagus, and the pathological stage was T3N2M0. The patient showed a metastatic mediastinal lymph node 4 months after the surgery.ConclusionBilateral thoracoscopic esophagectomy in the prone position can be safely performed, and it might be an alternative curative surgery for esophageal cancer. However, both our cases showed metastasis in the early postoperative period. The long-term outcome and significance of dissection of lymph nodes in the DTA in patients with esophageal cancer remains controversial. Further studies are required to establish the indications and efficacy of this therapeutic approach.     

Endobronchial Lipoma Accompanied with Primary Lung Cancer: Report of a Case

A 72-year-old man was found to have an endobronchial lipoma accompanied with primary lung cancer. A left lower lobectomy with a mediastinal lymph node dissection and a sleeve resection of the lingual bronchus with telescoping bronchial anastomosis were done. The pathological staging was T1N2M0, stage IIIA. A histological examination showed well-differentiated squamous cell carcinoma in segment 10, in addition to the presence of mature adipose tissue which was diagnosed to be a benign endobronchial lipoma originating from the lingual bronchus. The postoperative course was uneventful and the patient was discharged 13 days after the operation. However, he had a recurrence in the subcarinal lymph node, and died 8 months after surgery.

Three cases of transitional cell carcinoma in bladder diverticulum treated by a bladder-preserving approach

Three cases of transitional cell carcinoma (TCC) in the urinary bladder diverticulum were encountered during a period of 12 years and bladder preserving treatments were performed. Case 1: A 78-year-old man was admitted with a chief complaint of hematuria. Papillary tumors in the diverticulum of the right bladder wall were revealed (TCC, G3, T3N0M0). Intraarterial infusion chemotherapy was performed and complete remission was achieved. When a recurrent bladder tumor appeared 22 months later, transurethral resection was performed and there was no evidence of recurrence for 50 months. Case 2: A 60-year-old man was admitted with a chief complaint of gross hematuria. Cystoscopic examination revealed papillary tumors in a bladder diverticulum near the ureteral left orifice. Transurethral resection revealed TCC G2 and carcinoma in situ. Partial cystectomy, including the bladder diverticulum, and vesicoureteral neostomy was performed. The histological stage of the tumor was pTis and the wall of diverticulum possessed a thin muscle layer histopathologically. Twenty two months later, recurrence in the left bladder wall developed and transurethral resection and bladder instillation therapy were performed. For 21 months he had no evidence of recurrence. Case 3: A 59-year-old man was admitted with a chief complaint of hematuria. A solid tumor in the diverticulum of the bladder left wall was revealed. After 4 courses of intraarterial infusion chemotherapy, 41% remission was achieved and partial cystectomy was performed. Histopathological diagnosis was TCC G3, pT3b, INF-alpha, v (-), ly (-), and no muscle layer was found in the diverticulum. There was no evidence of recurrence 16 months after operation. By using the combination therapy, bladder preserving treatment is possible in the cases of bladder cancer arising in the diverticulum.

Carinal Reconstruction and Sleeve Right Upper Lobectomy Assisted with Extracorporeal Membrane Oxygenator for Non-small Cell Lung Cancer - A case report -

Bronchogenic carcinoma involving the carina has remained a challenging problem for thoracic surgeons. Carinal resection and reconstruction is limitedly indicated because this aggressive surgical approach has been reported to be associated with significant morbidity and mortality while long-term outcome has not been determined. Wesuccessfully performed carinal reconstruction and sleeve right upper lobectomy assisted with ECMO for a 60-year-old male with squamous cell carcinoma in the right upper lobe extending to the carina.     

Results of surgical resection for tracheobronchial cancer involving the tracheal carina

Objectives Carinal resection is a technically demanding procedure that is associated with significant morbidity and mortality. We review our experience of carinal resection and analyze its surgical results. Methods Between 1987 and 2004 a total of 35 patients underwent carinal resection for carcinoma involving tracheal carina. Surgical indications are primary non-small-cell lung cancer (NSCLC) in 29 patients, recurrence of NSCLC in 5, and tracheal cancer in 1. Operative procedures were divided into two groups: a reconstruction group (modified montage method in 14, one-stoma type in 2, montage type in 1); and a pneumonectomy group (tracheal sleeve in 10, wedge pneumonectomy in 8). Postoperative complications and survival of the two groups were evaluated. Results Three patients died postoperatively (8.5%). Major complications were noted in eight patients (22.8%), including three anastomotic stenoses, two pneumonias with respiratory failure, one dehiscence, one cardiac herniation, and one empyema. Six of these eight patients were in the reconstruction group. The overall survival was 42.5% at 2 years and 28.3% at 5 years. In patients with primary NSCLC, 7 of 16 patients with N0 disease survived more than 5 years, but all 13 patients with N1 or N2 disease died within 3 years. In the pneumonectomy group, 9 of 13 patients died within 2 years. Conclusion Carinal resection for tracheobronchial carcinoma is feasible with acceptable morbidity and mortality. Nodal involvement can be a potential contraindication for carinal resection. Careful selection of patients is crucial, especially when pneumonectomy is required.     

Jet ventilation via a Univent tube for sleeve pneumonectomy.

A 51-year-old man presented with a right upper lobe adenocarcinoma with carinal extension. He underwent a right sleeve pneumonectomy, which involved a carinal resection with anastomosis between the trachea and left main bronchus. This report describes the successful use of jet ventilation, administered via the lumen of the bronchial blocker of a Univent tube. During 15 min of carinal resection, oxygenation of his left lung was maintained with the bronchial blocker bridging the airway discontinuity.     

Collision cancer of squamous cell carcinoma and small cell carcinoma of the lung; report of a case

We report a rare case of a primary collision cancer in the lung consisting of squamous cell carcinoma and small cell carcinoma. A 65-year-old man with an abnormal shadow in the right S6 was diagnosed as squamous cell carcinoma by transbronchial lung biopsy. A right lower lobectomy with mediastinal lymph node dissection was performed. The pathological stage of squamous cell carcinoma was IIIA (T2N2M0). The other element diagnosed by pathological examination was small cell carcinoma of which pathological stage was IA (T1N0M0). Each element was clearly distinguished and touched each other. Following the operation, the patient received systemic chemotherapy against small cell carcinoma with cisplatin and irinotecan hydrochloride for 1 course, and cisplatin and etoposide for 3 courses. Since the prognosis of collision cancer is generally reported to be influenced by more advanced element of cancer, the prognosis of the present case is suspected to be dependent on the squamous cell carcinoma.     

A case of right B2 hillar lung cancer treated by sleeve segmentectomy

A 47-year-old male, a heavy smoker, was referred to our hospital after Class IV was detected by screening of sputum cytology. His chest X-ray film showed no abnormalities, but bronchoscopy revealed a small nodular lesion at the orifice of right B2. Squamous cell carcinoma was diagnosed by transbronchial biopsy. The clinical stage was I (T1N0M0), and S2 sleeve segmentectomy with lymph node dissection (R 2 b) was performed. The pathological stage was I (T1N0M0), and it was confirmed as early hilar lung cancer. There were no post operative complications and he is well without any evidence of recurrence 5 months after surgery. It may well be considered that this segmental bronchoplastic procedure is useful for cases with early stage squamous cell carcinoma of the segmental bronchus to preserve pulmonary function.     

Bladder-sparing surgery and continent urinary diversion using the appendix (Mitrofanoff procedure) for urethral cancer

We performed bladder-sparing surgery and continent urinary diversion in two patients with urethral cancer. The first patient was a 58-year-old man with bulbomembranous urethral cancer (squamous cell carcinoma, cT2N0M0). The second patient was a 77-year-old woman with urethral cancer invading the vaginal wall (transitional cell carcinoma with squamous cell carcinoma, cT3N0M0). After bladder-sparing urethrectomy, continent urinary diversion with appendicovesicostomy (Mitrofanoff procedure) was performed in the both patients. More than 4 years after the surgery, both patients were continent, had no trouble with catheterization, and experienced no recurrence of cancer. Bladder-sparing surgery and urinary diversion based on the Mitrofanoff procedure can be considered for appropriately selected patients with urethral cancer.     

Three primary cancers of pulmonary cancer, malignant melanoma and esophageal cancer; report of a case

A 61-year-old man, who had medical history of hepatitis type C, surgery for malignant melanoma of the lower limb, endoscopic mucosal resection for esophageal cancer, was pointed out a pulmonary nodule in the right middle lobe by surveillance computed tomography after 5 years of surgery for melanoma. Pathology of esophageal cancer was squamous cell carcinoma limited in mucosa without lymphatic nor venous invasion. The nodule gradually enlarged and respiratory endoscopic examination could not establish pathological diagnosis. Thoracoscopy-assisted pulmonary biopsy revealed squamous cell carcinoma, and right middle lobectomy with mediastinal node dissection was performed. Histological examination showed moderately differentiated squamous cell carcinoma without lymph node involvement. The stage of lung cancer was T1N0M0, stage IA. Although 9 months have passed since surgery for lung cancer, recurrence of each malignancy has not been detected.     

Combined Resection of Great Vessels or the Heart for Non-Small Lung Cancer

Objectives: The surgical indications for non-small cell lung cancer (NSCLC) infiltrating a great vessel or the heart are controversial. We assessed clinical features and surgical outcomes of patients with non-small cell lung cancer who underwent combined resection of a lung and great vessel.Methods: Fourteen patients underwent great vessel resection under a lobectomy (n = 9), sleeve lobectomy (n = 2), or pneumonectomy (n = 3) between 2000 and 2011, in whom the aorta was resected in 6, superior vena cava in 5, right atrium in 1, and left atrium in 2. The histological types were adenocarcinoma (n = 8) and squamous cell carcinoma (n = 6).Results: Complete resection was performed in 12 patients. Of all patients, 7 had pN0 disease, 2 had pN1, and 4 had pN2. The postoperative morbidity rate was 28.6% and mortality rate was 7.1%. The 5-year survival rate was 26.8% for all patients, 46.9% for those with an adenocarcinoma, 0% for those with a squamous cell carcinoma, 53.6% for those with pN0, and 0% for those with pN1-2.Conclusion: Resection of the great vessels and heart involved by NSCLC can be performed with acceptable morbidity and mortality, and results in prolonged survival in patients, with an adenocarcinoma or N0 status.
