M. Hartel
Background: Postoperative local water-filtered infrared A (wIRA) irradiation improves tissue oxygen partial pressure, tissue perfusion and tissue temperature, which are important in wound healing. Methods: The effect of wIRA irradiation on abdominal wound healing following elective gastrointestinal surgery was evaluated. Some 111 patients undergoing moderate to major abdominal surgery were randomized into one of two groups: wIRA and visible light irradiation (wIRA group) or visible light irradiation alone (control group). Uncovered wounds were irradiated twice a day for 20 min from days 2,10 after operation. Results: Irradiation with wIRA improved postoperative wound healing in comparison to visible light irradiation alone. Main variables of interest were: wound healing assessed on a visual analogue scale (VAS) by the surgeon (median 88·6 versus 78·5 respectively; P < 0·001) or patient (median 85·8 versus 81·0; P = 0·040), postoperative pain (median decrease in VAS score during irradiation 13·4 versus 0; P < 0·001), subcutaneous oxygen tension after irradiation (median 41·6 versus 30·2 mmHg; P < 0·001) and subcutaneous temperature after irradiation (median 38·9 versus 36·4 °C; P < 0·001). The overall result, in terms of wound healing, pain and cosmesis, measured on a VAS by the surgeon (median 79·0 versus 46·8; P < 0·001) or patient (79·0 versus 50·2; P < 0·001) was better after wIRA irradiation. Conclusion: Postoperative irradiation with wIRA can improve normal postoperative wound healing and may reduce costs in gastrointestinal surgery.

Malignant tumors of the nasal cavity and paranasal sinuses,

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 9 2002
Teri S. Katz MD
Abstract Purpose To evaluate the role of radiation therapy in patients with nasal cavity and paranasal sinus tumors. Materials and Methods Between October 1964 and July 1998, 78 patients with malignant tumors of the nasal cavity (48 patients), ethmoid sinus (24 patients), sphenoid sinus (5 patients), or frontal sinus (1 patient) were treated with curative intent by radiation therapy alone or in the adjuvant setting. There were 25 squamous cell carcinomas, 14 undifferentiated carcinomas, 31 minor salivary gland tumors (adenocarcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma), 8 esthesioneuroblastomas, and 1 transitional cell carcinoma. Forty-seven patients were treated with irradiation alone, 25 with surgery and postoperative irradiation, 2 with preoperative irradiation and surgery, and 4 with chemotherapy in combination with irradiation with or without surgery. Results The 5-year actuarial local control rate for stage I (limited to the site of origin; 22 patients) was 86%; for stage II (extension to adjacent sites (eg, adjacent sinuses, orbit, pterygomaxillary fossa, nasopharynx; 21 patients) was 65%; and for stage III (destruction of skull base or pterygoid plates, or intracranial extension; 35 patients) was 34%. The 5-year actuarial local control rate for patients receiving postoperative irradiation was 79% and for patients receiving irradiation alone was 49% (p = .05). The 5-, 10-, 15-, and 20-year ultimate local control rates for all 78 patients were 60%, 56%, 48%, and 48%, respectively. The 5-, 10-, 15-, and 20-year cause-specific survival rates for all 78 patients were 56%, 45%, 39%, and 39%, respectively. The 5-, 10-, 15-, and 20-year absolute survival rates for all 78 patients were 50%, 31%, 21%, and 16%, respectively. Of the 67 (86%) patients who were initially seen with node-negative disease, 39 (58%) received no elective neck treatment, and 28 (42%) received elective neck irradiation. Of the 39 patients who received no elective neck treatment, 33 (85%) did not experience recurrence in the neck compared with 25 (89%) of 28 patients who received elective neck irradiation. Most patients who received elective neck irradiation (57%) had stage III disease. Twenty-one (27%) of 78 patients had unilateral blindness develop secondary to radiation retinopathy or optic neuropathy; the complication was anticipated in most of these patients, because the ipsilateral eye was irradiated to a high dose. Four patients (5%) unexpectedly had bilateral blindness develop because of optic neuropathy. All four of these patients received irradiation alone. Conclusion Surgery and postoperative radiation therapy may result in improved local control, absolute survival, and complications when compared with radiation therapy alone. Elective neck irradiation is probably unnecessary for patients with early-stage disease. © 2002 Wiley Periodicals, Inc. Head Neck 24: 821,829, 2002 [source]


Prognostic significance of Bcl-2 and p53 expression in advanced laryngeal squamous cell carcinoma

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 4 2001
Michael Friedman MD
Abstract Background Proteins regulating the cell cycle and cell death are frequently abnormally expressed in cancer. Several of these, particularly p53 and Bcl-2, have been widely suggested as possible prognostic markers in diverse human malignancies. Their role in predicting outcome in squamous cell carcinomas of the head and neck is unclear and may depend on the location, stage, and treatment of the tumor. Methods To assess this question specifically for advanced squamous cell carcinoma of the larynx, we studied 69 patients with stage III or IV tumors, all but 6 of whom were treated with surgery plus postoperative irradiation by a single physician. We studied the patients retrospectively to test the association between expression of Bcl-2 and p53, as assessed by immunohistochemistry, with treatment outcome and survival. Results Twenty of the 69 patients died from their tumor (poor outcome); the rest were alive and tumor free at the last follow-up or died of unrelated causes without clinical tumor recurrence (good outcome). Fourteen tumors had detectable Bcl-2 expression, including 8 scored as overexpressors. Thirty-nine tumors overexpressed p53. Expression of neither Bcl-2 nor p53 was associated with outcome, overall survival, or disease-free survival. Only tumor stage was significantly associated with outcome and disease-free survival. Conclusion These data indicate that assessing expression of p53 or Bcl-2 is unlikely to be prognostically useful for surgically treated advanced laryngeal carcinoma. © 2001 John Wiley & Sons, Inc.

The clinical relevance of epithelial dysplasia in the surgical margins of tongue and floor of mouth squamous cell carcinoma: an analysis of 37 patients

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 1 2002
M. Weijers
Abstract Background:, The clinical relevance of the presence of epithelial dysplasia in the margins of surgically removed oral squamous cell carcinoma is still unclear. Method:, In a retrospective study, the presence of mild or moderate epithelial dysplasia in the surgical margins of tongue and floor of mouth squamous cell carcinoma was examined histologically. Patients with tumor cells within 0.5 cm of the surgical margins were excluded. Also patients with severe dysplasia were excluded, as this is usually regarded as carcinoma in situ. Patients that received postoperative irradiation were also excluded. Only patients who completed a follow-up period of five years were included. All together, a total number of 37 patients fulfilled the inclusion criteria. Results:, Epithelial dysplasia was observed in 7 out of the 37 patients. Five of these patients, and two of the 30 patients with no dysplasia, had a local recurrence (P < 0.01). Conclusion:, The presence of mild or moderate epithelial dysplasia in the margins of surgically removed oral squamous cell carcinoma carries a significant risk for the development of local recurrence. However, it should be noted that this study was of a retrospective nature and that the group of patients with epithelial dysplasia in the surgical margins was rather small. On the other hand, the inclusion criteria were somewhat strict, by limiting the oral subsite to tongue/floor of mouth, by excluding patients in whom tumors cell were found within 0.5 cm of the surgical margins and by excluding patients who received postoperative radiotherapy, amongst others.

Endoscopic Vertical Partial Laryngectomy,

THE LARYNGOSCOPE, Issue 2 2004
R Kim Davis MD
Abstract Objective: To explain the significant difference between microlaryngoscopy with cordectomy and endoscopic vertical partial laryngectomy (EVPL), to describe the efficacy of EVPL on T1b and T2 glottic squamous cell carcinoma, and to evaluate EVPL with postoperative irradiation in T2 glottic cancer with impaired true vocal cord mobility. Study Design: Retrospective review. Methods: Twenty-six patients seen at the University of Utah Health Science Center between 1987 and 2000 with bilateral T1 (T1b) or T2 squamous cell carcinoma of the glottic larynx underwent EVPL. T2 cancers were classified as follows: a = unilateral disease, b = bilateral disease; i = impaired mobility. T1b and T2a glottic cancer patients received surgery alone, whereas impaired mobility patients (T2ai + T2bi) patients received surgery followed by planned postoperative irradiation. Patients were assessed for primary site control, perioperative and long-term complications, and ultimate cancer control. Results: Survival in the total group was 88.5%, with local control at 92.3%. The two recurrent patients were salvaged by total laryngectomy. For the whole group, anterior commissure involvement was present in 57.7% (15 of 26). Thirteen T2 (5 T2ai + 8 T2bi) carcinoma patients underwent combined therapy, with 8 (61.5%) of these patients having anterior commissure involvement. Two of these patients were upstaged at surgery, one to T3 and one to T4. Local control was 84.5%. Thirteen patients were treated by surgery only, with five of these patients having failed previous irradiation. Survival was 92.3% and local control 100%. This group included two T2bi patients, two patients upstaged to T4 on the basis of extension beyond the subglottis to the anterior wall of the trachea, 3 T2b, and 6 T2a patients. Anterior commissure involvement was seen in 7 (53.8%) of these patients. Conclusions: EVPL alone controlled all T1b and T2a glottic cancer patients, even in the presence of greater than 50% anterior commissure involvement. The significant difference between EVPL and classical microlaryngoscopy with cordectomy was carefully described. EVPL with planned postoperative irradiation resulted in an 85% local control rate in clinically staged T2ai and T2bi cancer patients, including the three upstaged patients. [source]


Bilateral Squamous Cell Carcinoma of the External Auditory Canals,

THE LARYNGOSCOPE, Issue 6 2002
Stephen G. Wolfe
Abstract Objectives To report a case of bilateral squamous cell carcinoma of the external auditory canals and to present a management algorithm for this difficult clinical scenario. Study Design Case report and literature review. Methods The study comprises a case report of a 69-year-old man who initially presented with complaints of bilateral otorrhea, left-sided otalgia, and a left-sided hearing loss. Following attempted treatment of a presumed case of otitis externa, biopsy of both external auditory canals revealed squamous cell carcinoma. A computed tomography scan demonstrated marked abnormal soft tissue in the left external auditory canal with no bony erosion and thickening of the soft tissue in the right external auditory canal. Results The left-sided lesion required a lateral temporal bone resection, a partial superficial and deep-lobe parotidectomy, and postoperative irradiation. The right-sided lesion was more limited and was managed with a lateral temporal bone resection and tympanoplasty for hearing preservation. Conclusions Bilateral squamous cell carcinoma of the external auditory canals is an extremely uncommon but aggressive malignancy that may present with symptoms similar to a case of otitis externa, and this can result in delays in proper diagnosis. Early recognition is essential because management and prognosis are determined by the extent of the lesion. [source]


Lateral mammaplasty reconstruction after surgery for breast cancer,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 10 2009
M. Ballester
Background: Up to 60 per cent of cancers develop laterally in the breast and breast-conserving surgery frequently produces superolateral nipple,areolar complex (NAC) distortion aggravated by postoperative irradiation. Correction is technically demanding and the outcomes are variable. Lateral mammaplasty may allow wider excision margins and prevent such deformities. Methods: This was a review of 86 consecutive patients who had lateral mammaplasty: combined wide tumour excision with NAC repositioning on a reliable dermoglandular pedicle. Simultaneous axillary surgery was performed via a separate or combined incision. Aesthetic outcomes were assessed. Results: The median age of the women was 54 (range 29,75) years; 55 (64 per cent) had palpable tumours and 73 (85 per cent) underwent simultaneous axillary surgery. Median radiological and histological tumour sizes were 29·8 and 33·6 mm, respectively, and median weight of excised tumour was 150 g. Two patients required haematoma evacuation. Eleven women required revisional surgery for involved or close margins. Aesthetic outcomes were excellent or good in 93 per cent. Conclusion: Lateral mammaplasty produced clear margins in 87 per cent of women. It is an option when a deformity is anticipated after breast-conserving surgery, and is particularly valuable when neoadjuvant chemotherapy has downgraded a large tumour.

The role of postoperative radiotherapy for the treatment of gangliogliomas

CANCER, Issue 2 2010
Dirk Rades MD
Abstract BACKGROUND: Because of their rarity, no prospective studies have been performed regarding gangliogliomas. The optimal treatment regimen is unclear. In this study, the authors compared 4 therapies for local control (LC) and overall survival (OS) in patients with ganglioglioma. METHODS: In 402 patients with ganglioglioma, outcomes were compared for patients who underwent gross total resection alone (GTR) (n = 188), GTR plus radiotherapy (GTR + RT) (n = 21), subtotal resection alone (STR) (n = 113), and STR plus RT (STR + RT (n = 80). Age, sex, tumor site, and histologic grade also were investigated. Subgroup analyses were performed for both low-grade and high-grade tumors. RESULTS: The 10-year LC rates were 89% after GTR, 90% after GTR + RT, 52% after STR, and 65% after STR + RT (P < .001); and the 10-year OS rates were 95%, 95%, 62%, and 74%, respectively (P < .001). After STR, irradiation significantly improved LC (P = .004) but not OS (P = .22). After GTR, irradiation did not significantly improve LC (P = .23) or OS (P = .29). On multivariate analyses, LC and OS were associated with therapy and pathologic grade, and OS also was associated with tumor site. In low-grade tumors, STR + RT resulted in better LC (P = .016) but not better OS (P = .18); and, after GTR, LC (P = .28) and OS (P = 1.0) were not improved with postoperative radiotherapy. In high-grade tumors, STR + RT resulted in better LC (P = .016) but not better OS (P = .41); after GTR, LC (P = .56) and OS (P = .61) were not improved with irradiation. CONCLUSIONS: According to this review, GTR should be performed whenever safely possible and does not require postoperative irradiation. If only STR is achieved, then RT improves LC of both low-grade and high-grade tumors and, thus, should be considered seriously. Cancer 2010. © 2010 American Cancer Society. [source]
