JOURNAL FREE ACCESSSpinal accessory nerve palsy caused by the retractor during operation is often observed even in functional neck dissections in which the spinal accessory nerve was spared, not to mention radical neck dissections. Therefore the degree of spinal accessory nerve palsy should be examined for the necessity of rehabilitation after neck dissections whether spinal accessory nerve was spared or not. It is useful for estimate of the degree of spinal accessory nerve palsy that the range of arm abduction test and lateral-lower shift of scapla examined by inspection and palpation. In actual rehabilitation , physical therapy about range of motion at shoulder joint that prevent joint adhesion around shoulder is important. To revise the lateral-lower shift of scapla, this rehabilitation should be started at supine position which the weigh of upper limbs was reduced. Afterwards, the active arm abduction test results were almost recovered in neck dissections in which the accessory nerve was preserved at around 6 months postoperatively. The arms movement without a big hindrance in daily life could be provided by rehabilitation even in neck dissections in which the accessory nerve was sacrificed.View full abstractDownload PDF (1709K) -

JOURNAL FREE ACCESSThirty-one cases of hypopharyngeal cancer with neck dissection preceding radiation and 16 cases of hypopharyngeal cancer with neck dissection for locoregional recurrences after radiation were reviewed in order to make comparative evaluations of difficulty in surgical operation, postoperative complications, laryngeal preservation rate, and cause specific 5-year survival rate retrospectively. And QOL after neck dissection was additionally evaluated through the questionnaire. Since neck dissection preceding radiation for hypopharyngeal cancer may be superior to neck dissection for radiation failure, with easy surgical approach an non-lymphoid tissue preservation, that modality can be a reasonable choice of treatment for patients with nodal lesions, which are probably difficult to treat with radiation alone. Even though further investigation on QOL questionnaire is necessary, this modality can make a contribution to the neck and shoulder condition after neck dissection.View full abstractDownload PDF (815K) -

JOURNAL FREE ACCESSWe evaluated the effect of planned neck dissection (PND) after concurrent chemoradiotherapy (CCRT) on quality of life (QOL) by using a self-administered neck dissection questionnaire and an arm abduction test. Subjects are fourteen patients who had undergone CCRT followed by planned selective neck dissection for the treatment of mesopharyngeal and hypopharyngeal cancer. The findings of the survey were compared with thirty-two patients who had undergone CCRT alone. Patients without PND had better scores on measures of pain, constriction, numbness and appearance of the neck, but had no advantage about arm abduction. After PND, the patients who had dissected dominant hand side had lower satisfaction compared with those who had dissected non-dominant hand side.View full abstractDownload PDF (1031K) -

JOURNAL FREE ACCESSThis study was objected to elucidate the proper treatment for cervical lymph nodes with stageII tongue cancer. The subjects were 180 patients with stage II tongue cancer being treated by surgery for the first time (1998-2003, Ministry of Health, Labour and Welfare Cancer Study Group, 21 institutions). Their clinico-pathological data were retrospectively reviewed. Latent metastases were occurred 32% of the patients. A review of the histopathological sites in the cases with latent metastases mostly revealed within the area at level I, level II and level III. Latent metastases occurred more frequent in the group in which tumor thickness was 6 mm or more than in the group in which tumor thickness was 5 mm or less statistically. Postoperative cervical metastasis occurred lesser in the group that had undergone elective neck dissection than in the group that had not, and the difference between the groups was significant (p=0.03). However, there was no significant difference in the cause specific survival. We concluded that elective neck dissection is indicated in cases in which tumor thickness exceeds 6 mm. Moreover, we concluded that the appropriate area of elective neck dissection is level I, level II, and level III on the affected side, the most common sites of latent metastasis. However, the meaning is still controversial, becase there was no significant difference in the cause specific survival.View full abstractDownload PDF (1064K) -

JOURNAL FREE ACCESSSentinel node (SN) biopsy has been taken part of decision of neck dissection for early stage carcinoma of tongue since 2000 in our department. A series of 25 cases of stage I and II carcinoma of tongue was analyzed prospectively. SN was detected in all 25 cases. We chose two kinds of radio tracer (99m labeled rhenium colloid and 99m labeled phytate). Average number of detected SN with rhenium (3.7) was different from that with phytate (2.3). Five of 25 cases were upstaged as the result of a positive SN biopsy. Post operative submandible node metastasis (POSNM) occurred in two of 20 cases with negative SN. As countermeasure to avoid POSNM, we use a lead plate to separate the cervical area from the injected oral area, and after then, POSNM did not occurred in 12cases. Although three of five positive neck metastasis cases had no recurrence, there were two cases with recurrence of carcinoma under the mucosa of oral floor. These two cases did not undergo pull through method for primary resection of the tongue carcinoma. Therefore, we recommend surgery for usually for advanced stage in a positive case with SN biopsy.View full abstractDownload PDF (823K) -

JOURNAL FREE ACCESSObjective : To prove that the preventive neck dissection for N0 oral carcinoma is useful or not. Patients and Methods : Eighty-seven patients N0 oral cancer, initially operated in Kyoto University Hospital between 2003 and 2008, were retrospectively studied. Among them 44 patients underwent primary resection and preventive neck dissection and 43 underwent only primary resection. Survival rate and results of salvage operation for lymphnode were compared in these groups ; preventive-ND group and non-ND group. Result : Three-year survival of Stage I · II oral carcinoma is 96.2% in preventive-ND group and 79.3% in non-ND group (non- significance p=0.146). Half of patients of lymphnode recurrence were not salvaged by neck dissection. Conclusion : Preventive neck dissection for N0 oral carcinoma is useful, as it is difficult to control lymphnode recurrence by salvage operation.View full abstractDownload PDF (703K) -

JOURNAL FREE ACCESSRecently, chemoradiation (CRT) for head and neck cancer has played an important role as a definitive organ preservation treatment strategy. Although planned neck dissection (PND) has a possibility to improve locoregional control and survival, neck dissection after CRT is associated with an increased incidence of post surgical complications and deterioration of quality of life. Because of this, adaptation of PND is still controversial. In this review article, we explore what kind of patients should receive neck dissection after CRT and how to rule out the patients who are not necessary to receive neck dissection after CRT using diagnostic imaging technology like CT, MRI and FDG-PET.View full abstractDownload PDF (691K) -

JOURNAL FREE ACCESSObjective : Concurrent chemoradiotherapy (CCRT) is one of the recent emerging modalities for advanced squamous cell carcinoma of the head and neck (HNSCC). However some of the patients treated by CCRT have residual or recurrent cervical lymph nodes. In these cases, neck dissection is considered to be useful in the point of locolegional control and disease free survival. This study aims to analyze neck control rate by CCRT and usefulness of the neck dissection after CCRT for HNSCC. Method : The medical records of 69 consecutive patients (stage III : 4%, stage IV : 96%) treated with CCRT for SCCHN (hypopharynx : 40, oropharynx : 25, larynx : 4) from 2003 through 2007 were reviewed. Results : Clinical complete response (CR) rates of N1, N2a, N2b, N2c and N3 were 75%, 100%, 71%, 74% and 43% respectively. Among the patients with complete neck response, only 2 patients (5 %) had an isolated neck recurrence. Eleven patients underwent surgical neck procedures including 7 planned neck dissections and 4 salvage neck dissections. All the 11 patients with neck dissections had good regional control except 1 case. There were a few minor complications such as wound infection and laryngeal edema. Conclusion : Patients who have a complete clinical regional response to CCRT have a low probability of an isolated recurrence in the neck. Planned and salvage neck dissections can be safely performed and considered to be useful in the point of regional control after intensive CCRT.View full abstractDownload PDF (985K) -

JOURNAL FREE ACCESSChemoradiaotherapy (CRT) became the standard treatment for head and neck cancer, because of its good efficacy and functional preservation. Unfortunately, some of the cases treated by CRT have residual or recurrent tumors in cervical lymph nodes. Therefore salvage surgery for residual or recurrent neoplasm after the CRT is important. We examined neck dissection cases after the CRT which went in our hospital. The neck dissection cases after the CRT in our hospital were 14 of 794(1.8%) patients. Even if it included a case given CRT in another hospital, there were 29 of 867(3.3%) patients. It was little number of cases than we expected. The neck dissection after the CRT in our hospital mainly chose radical neck dissection. However, it came to be thought that elective neck dissection was enough for the neck dissection after the CRT. The disease-specific five-year survival rate of the neck dissection cases after the CRT was 49.3%, in our hospital. It was thought that we were worth trying a salvage surgery without giving it up.View full abstractDownload PDF (811K) -
