Atraumatic tooth extraction in patients taking bisphosphonates: a review of literature and experience with three cases.

PURPOSE: Regev et al. first re-introduced the method of atraumatic tooth extraction with orthodontic elastics in 2008. Since then, the method has been mentioned regularly in literature. Nevertheless, the need for additional more detailed information remains. METHODS: We present a review of literature and a retrospective analysis of our three patients receiving bisphosphonate medication. Two of our patients suffered from bisphosphonate-related osteonecrosis of the jaw (BRONJ). All three patients underwent atraumatic tooth extraction, which we describe in detail. RESULTS: Regev et al. reported satisfactory results using the novel method. We removed six teeth in two patients with continued chemotherapy or bisphosphonate therapy in a time span of 26.2 ± 16.4 weeks successfully. None of the patients developed exposed bone in the follow-up (7.4 ± 0.2 months). In one case, the technique had to be discontinued due to increasing tooth soreness. CONCLUSIONS: Atraumatic tooth extraction seems to be a safe method to prevent bone exposure, even in cases with BRONJ. The time required of our patients for exfoliation exceeded the time mentioned in literature considerably. This proved to be a major limitation. Our cases showed that patients with good compliance, no sore teeth, or painful BRONJ lesions, benefited from atraumatic tooth extraction. One of the method's major advantages might be the possibility to continue chemotherapy and bisphosphonate therapy throughout the treatment.

[Single French centre retrospective analysis of local control after high dose radiotherapy with or without chemotherapy and local control for Pancoast tumours]. / Analyse rétrospective monocentrique française du contrôle local des cancers bronchiques non à petites cellules de l'apex après radiothérapie de haute dose avec ou sans chimiothérapie.

PURPOSE: Superior sulcus non-small cell lung cancer represents less than 5% of all lung cancers and is a challenge for the physicians because of clinical presentation, treatments related toxicities and poor prognosis. The aim of this preliminary retrospective report is to present outcomes of patients affected by a superior sulcus non-small cell lung cancer, treated by high dose radiotherapy (>60 Gy) with or with our chemotherapy. PATIENTS AND METHODS: All adult inoperable or unresectable patients (≥18 years) with a clinical and radiological diagnosis of superior sulcus non-small cell lung cancer treated in our department by radiotherapy with or without chemotherapy were retrospectively analysed. Primary endpoint was the local control. Overall survival, metastasis free survival and toxicity rates were also analysed and reported. RESULTS: From January 1999 to June 2009, 12 patients were treated by exclusive high-dose radiochemotherapy. Median age was 53 years (range: 33-64 years); mean follow-up time was 20 months (range: 2-75 months). Mean local control, overall survival and metastasis free survival were 20.2, 22 and 20 months, respectively. At the time of this analysis, seven patients died of cancer and three of them presented only a metastatic disease progression. One patient died of acute cardiac failure 36 months after the end of radiochemotherapy and was disease free. Treatment was well tolerated and any acute and/or late G3-4 toxicity was recorded (NCI-CTC v 3.0 score). CONCLUSION: This analysis confirms the interest of exclusive high-dose radiochemotherapy in treating inoperable superior sulcus non-small cell lung cancer patients, in achieving good local control and overall survival rates.

[Chest wall surgery]. / Cirugía de la pared torácica.

Despite the numerous differences among the distinct diseases of the chest wall, the surgery of this area shows certain common features. Treatment has progressively changed in the last few years due to advances in diagnostic techniques, minimally invasive procedures and reconstruction materials, and especially due to the multidisciplinary management of many diseases. Nuss' minimally invasive correction of pectus excavatum has gained devotees, although open approaches are performed with increasingly small incisions, almost comparable to the lateral incisions in Nuss' technique. Surgeons supporting the open approach also cite the evident disadvantages of the need for a steel implant for 2 or 3 years and for a second intervention to remove this implant. En-bloc resections with reconstruction using materials, which are increasingly better and covered by myocutaneous grafts in collaboration with plastic surgery departments, constitute a major advance in the treatment of chest wall tumors. Trimodal therapy for Pancoast tumors, consisting of induction chemotherapy and radiotherapy and subsequent surgical treatment of the tumor, currently provides the best results in terms of resectability and survival.

Definitive radiotherapy plus regional hyperthermia with or without chemotherapy for superior sulcus tumors: a 20-year, single center experience.

PURPOSE: To assess the efficacy and toxicity of definitive radiotherapy (RT) plus regional hyperthermia (HT) in treating superior sulcus tumors (SSTs), and to identify predictors of positive outcomes. METHODS AND MATERIALS: Twenty-four patients with SSTs treated with definitive RT plus regional HT were retrospectively analyzed. The median total dose of RT was 70 Gy. All patients were treated with an 8-MHz RF-capacitive heating device. Twelve of 24 (50%) patients also underwent chemotherapy. Those with either subcutaneous fat measuring 2.5 cm or greater, or any other serious complications did not undergo this therapy. RESULTS: Overall survival, local control, and distant metastasis-free survival rates at 3 years were 47%, 55%, and 71%, respectively. Chemotherapy and younger age (<65 years) were significant predictors of the overall survival rate. Clinical stage (IIB) was a statistically significant prognostic indicator for local control survival rate. Toxicities were mild, with Grade 3 dermatitis seen in one patient. CONCLUSIONS: Definitive RT plus regional HT with chemotherapy may be a promising treatment for SSTs. The results justify further evaluation with detailed treatment protocols in a large number of patients.

Tension pneumocephalus complicating Pancoast tumor resection.

A case of tension pneumocephalus following Pancoast tumor resection is presented. Conservative management was successful. The presenting symptoms and signs, diagnostic methods and options for treatment are discussed and reviewed.

[A case of lung adenocarcinoma of pancoast type successfully treated with concurrent chemoradiotherapy].

We reported a case of lung adenocarcinoma of Pancoast type that was successfully treated with chemoradiotherapy. A 66-year-old man was admitted to our hospital because of back pain. Chest computed tomography (CT) showed a Pancoast tumor on the left side. Using transbronchial needle aspiration, we diagnosed lung adenocarcinoma (cT3N0M0). The patient received chemoradiotherapy simultaneously(carboplatin AUC5 and irinotecan 60 mg/m2). There are no findings of tumor recurrence 8 years after chemoradiotherapy. This patient was successfully treated with concurrent chemoradiotherapy, which is suggested to be a useful therapy for Pancoast tumor.

Drug-eluting stent treatment of a radiation-induced left internal mammary arterial graft stenosis.

A 62-year-old man underwent radiotherapy to the left upper chest for treatment of Pancoast syndrome on a background of previous coronary artery bypass grafting 12 years earlier. Within 1 year, he developed significant stenoses of both the left internal mammary artery (LIMA) graft and ostial left vertebral artery, presumably related to therapeutic radiation exposure. Initially diagnosed using computed tomography coronary angiography, the patient underwent percutaneous coronary intervention and insertion of a drug-eluting stent (DES) to the ostium of the LIMA graft via a left radial approach. He remains clinically well at 6-month follow-up. This is the first reported case in the literature of DES treatment of a radiation-induced vascular stenosis; however, the incidence of cardiovascular disease is elevated in such cases. In patients with a prior history of mantle radiation, consideration should be given to the routine assessment of internal mammary conduits prior to coronary artery bypass surgery.

[Long-term results of the multidisciplinary surgical treatment of non-small-cell bronchial carcinoma in the superior sulcus (Pancoast tumour): a retrospective study]. / Langetermijnresultaten van de multidisciplinaire chirurgische behandeling van niet-kleincellig bronchuscarcinoom in de thoraxkoepel (pancoasttumor); retrospectief onderzoek.

OBJECTIVE: To establish the long-term results of a combination of radiotherapy or chemoradiotherapy and surgery for the treatment of patients with a Pancoast tumour in the Erasmus MC-Daniel den Hoed, Rotterdam, the Netherlands, with special attention for the prognostic factors. DESIGN: Retrospective. METHODS: During the period from 1 January 1991 to 31 December 2004, 36 patients underwent surgical treatment combined with radiotherapy or chemoradiotherapy for a non-small-cell bronchial carcinoma with invasion of the superior sulcus. The study was terminated on 31 January 2006. The data were analysed according to the intention-to-treat principle, with overall survival and disease-free survival as the outcome variables. Cox regression analysis revealed differences between the subgroups on the basis of which prognostic factors could be studied. RESULTS: 36 patients with a non-small-cell bronchial carcinoma invading the superior sulcus (Pancoast tumour) underwent multidisciplinary treatment consisting of pre-operative radiotherapy (since 2002 concomitant chemoradiotherapy), superior-sulcus resection and (partial) lung resection with intra-operative brachytherapy. 2 patients died postoperatively. In 80% of the patients there was a positive histological effect of the preoperative treatment. The median follow-up was 26 months. The 2-year overall and disease-free survival was 45 and 31%, respectively, and at 5 years this was 28 and 19%. These results were comparable with those for stage IIB lung cancer without invasion. Favourable prognostic factors were: at least 75% necrosis of the tumour after pre-treatment, lack of positive mediastinal lymph nodes, and younger age.

[Complete resection of Pancoast tumor while receiving preoperative concurrent chemoradiotherapy (CCRT) as an induction therapy--report of a case].

A 60-year-old man complaining of right shoulder pain and numbness of right arm was diagnosed with Pancoast tumor (invasive right apical lung cancer). Chest CT scan showed a tumor, 5 cm in diameter, in the right apex invading the right posterior chest wall. The patient received preoperative CCRT (RT: 40 Gy/20 Fr, cisplatin: CDDP and etoposide: ETP), resulting in tumor regression (PR). The patient underwent right upper lobectomy (ND 2a), partial resection of the 1st-3rd ribs and Th 1 nerve. Pathological examination demonstrated no live cancer cells and organization of necrotic tissue in the lung and intercostal region (Ef. 3). The patient received postoperative chemotherapy (CDDP+ETP) and was discharged. He did well without any tumor recurrence for 1 year postoperatively. CCRT seems effective and is one of the standard treatments for Pancoast tumor.

Multimodality therapy for Pancoast tumor.

The management of Pancoast tumors has challenged surgeons and radiation and medical oncologists over several decades. Retrospective studies have raised a greater awareness of the importance of positive N2 lymph nodes in terms of prognosis and treatment decision making. While patients with positive N2 lymph nodes have generally been excluded from trials of preoperative chemoradiation for superior sulcus tumors, the potential of surgery for these patients is still being evaluated. The role of PET for initial staging as well as for assessment of disease response to induction therapy continues to evolve. The use of combined treatment modalities has enhanced the progress in successfully treating Pancoast tumors. The historical data showing improved results with a combination of surgery and radiation compared with surgery alone for patients with positive N2 nodes provides the basis for several important clinical trials that integrate the use of chemotherapy into the treatment paradigm. The Southwest Oncology Group and Japanese Clinical Oncology Group have shown dramatic improvements in complete resection rates following a neoadjuvant course of combined chemotherapy and radiation therapy compared with historical series. We discuss relevant ongoing clinical trials that include consolidative taxane-based chemotherapy and the role of prophylactic cranial irradiation in complete responders. Future potential areas of investigation, including the role of surgery for patients with N2-positive disease and the use of imaging to assess response after induction therapy, are discussed.

The lung cancer in form of tumor of Pancoast affects about 200 Cubans annually and it is still considered incurable for many in Cuba. In the National Institute of Oncología and Radiobiología he/she was carried out a prospective study of technological introduction that consisted on radio-chemotherapy preoperatoria and enlarged surgery, applied to patient with lung cancer in form of tumor of Pancoast in stage potentially curable. Between January of 1991 and March of 2004 36 patients were included (28 men, 8 women, with age 51,6 year-old average, minimum of 34 and maxim of 69). The cellular types were: adenocarcinoma (21), epidermoide (12), carcinoma of big cells (2), carcinoma indiferenciado (1). there were 28 cases in stages IIB, 4 in stage IIIA and 4 in stage IIIB. They not happened 3 surgical deaths related with the operative technique. The survival to the 3 and 5 years was of 57 percent and 38 percent, respectively. The combined treatment of radio-chemotherapy and enlarged surgery achieves the crazy-regional control and the survival prolonged in many patients with tumor of Pancoast in located stage(AU)

High-dose radiotherapy in trimodality treatment of Pancoast tumors results in high pathologic complete response rates and excellent long-term survival.

OBJECTIVE: We sought to study the clinical characteristics and outcomes of patients treated with a surgery-inclusive multimodality approach for Pancoast tumors. METHODS: Clinical records of patients with Pancoast lung cancer who were enrolled for multimodality treatment between 1993 and 2003 at our institution were reviewed retrospectively. RESULTS: Thirty-six patients completed neodjuvant chemoradiation followed by en bloc surgical resection, whereas one patient received high-dose radiation alone followed by surgical intervention. There were 22 men and 15 women. Thirty-four lobectomies and 3 pneumonectomies were performed. Pretreatment non-small cell lung cancer stages were IIB, IIIA, IIIB, and IV (presenting with solitary brain metastasis) in 18, 8, 6, and 5 cases, respectively. R0 resection was achieved in 36 (97.3%) patients. Operative mortality was 2.7% (n = 1). High-dose radiotherapy was successfully tolerated in all but 1 patient. Mean total radiation dose was 56.9 Gy. Pathologic complete response was found in 40.5% (n = 15) of patients. Recurrences were found in 50% (n = 18) of patients. Brain metastasis was the most common recurrence (n = 9), followed by other distant recurrences (n = 4) and local recurrences (n = 5). Median survival time for the group is 2.6 years, and median survival time (pathologic complete response) is 7.8 years. It is noteworthy that median survival time of patients with positive pretreatment lymph nodes (12 patients) was not reached. CONCLUSIONS: Surgical resection of Pancoast tumors after neoadjuvant high-dose radiation and chemotherapy can be safely performed. High-dose radiation in trimodality treatment is well tolerated and might be beneficial. Similar to other studies, late central nervous system relapse is problematic and indicates a need for assessing the role of prophylactic cranial irradiation in this disease.

[Pneumocephalus and cerebrospinal fluid fistula following removal of a superior sulcus tumor (pancoast tumor)]. / Neumoencéfalo y fístula de líquido cefalorraquídeo tras resección de tumor del sulcus superior (tumor de Pancoast).

Pneumocephalus resulting from a subarachnoid-pleural fistula following resection of a pulmonary neoplasm is a very rare postoperative complication: we have found only 17 cases in the literature. We report the case of a 65-year-old man diagnosed with a superior sulcus tumor who underwent a left upper lobectomy and costal resection following neoadjuvant radiation therapy. Soon after surgery, the patient developed a subarachnoid-pleural fistula and pneumocephalus that required reoperation and drainage. Recurrence was suspected when chronic aseptic meningitis developed. Another thoracotomy was required to resolve the complication.

Pancoast's syndrome due to metastatic carcinoma from the stomach.

We describe here a case of Pancoast's syndrome due to metastatic carcinoma from the stomach. Although obtaining a tissue diagnosis is often difficult with apical lesions, transbronchial or percutaneous needle biopsy is the procedure of choice since a certain number of these cases are potentially curable.

Changes in the treatment of Pancoast tumors.

Our understanding of superior sulcus tumors has evolved over time. The unique feature of Pancoast tumors is their location, in which the anatomy poses limitations to resection. Many resections are found to be incomplete, and the majority of recurrences have involved local failure. New surgical approaches allow greater flexibility according to tumor location and may improve these outcomes. Furthermore, new approaches permit complete resection of tumors involving vertebral bodies or the neural foramina. Traditionally, preoperative radiotherapy has been used, but a recent prospective phase II study suggests that preoperative concurrent chemoradiotherapy improves the rate of complete resection, local recurrence, and intermediate-term survival.

Concomitant weekly cisplatin and thoracic radiotherapy for Pancoast tumors of the lung: pilot experience of the San Antonio Cancer Institute.

Pancoast (superior sulcus tumors) comprise a subset of non-small-cell lung cancers that have a unique clinical presentation by virtue of the locoregional pattern of disease progression. We herein report a brief report on our group's pilot experience in managing these challenging lung neoplasms with an aggressive concomitant modality approach. These results and those of the recent Southwest Oncology-lead Intergroup prospective phase 2 trial (SWOG-9416/INT-0160) support the use of concomitant chemoradiation followed by an attempt at surgical resection.
