Management of squamous-cell carcinoma of the lip

Primary cN0 lip squamous cell carcinoma and elective neck dissection: Systematic review and meta-analysis

BACKGROUND

Management of clinically negative lymph nodes (cN0) in primary lip squamous cell carcinoma (SCC) has always been a controversial topic.

METHODS

A systematic review of English-language electronic databases using Medline, Embase, Cochrane library, Google Scholar, SCI, and specific journals on the subject matter was done. Only the studies mentioning primary nonmetastatic lip SCC with cN0 neck treated by surgery only and having at least 2 years of follow-up data were selected. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for reporting systematic reviews and meta-analysis was followed.

RESULTS

The pooled estimate of occult metastasis in neck dissected specimen was 0.17 (95% confidence interval [CI], 0.10-0.28) and that of delayed nodal metastasis in patients without neck dissection was 0.08 (95% CI, 0.01-0.18).

CONCLUSION

The results do not prove sufficient to justify elective treatment of the neck in primary cN0 lip SCC and close observation would be a viable option in such cases. © 2014 Wiley Periodicals, Inc. Head Neck 37: 1392-1400, 2015.

Surgical management of primary carcinomas of the lower lip

Carcinomas of lower lips are common neoplasms of the muco-cutaneous junction. Surgical resection of these tumors has the advantages of permitting histologic examination of the margins, achieving excellent cure rates, and yielding good aesthetic and functional results. We present the fundamental surgical procedures for management of pre-cancerous and primary cancerous neoplasms of the lower lip with which the surgical dermatologist should be familiar. These procedures may be done with local anesthesia in an outpatient surgical office. The techniques and case examples we describe include vermilionectomy and mucosal advancement, V-wedge resection, pentagonal wedge resection, and vermilionectomy combined with wedge resection.

Surgical treatment of two squamous-cell carcinomas in the same lip: case report

We report one patient who developed two squamous-cell carcinomas on different parts of the lower lip. The tumors were excised by the UV technique, a variation of the V-shped excision. We repaired the defect caused by excision of the first lesion by direct closure and that caused by extirpation of the second lesion by use of a transposition flap (Abbe-Estlander technique).

A short review of some methods of excisions from and reconstructions of lower lips

Various methods of excising lesions from the lower lip are discussed and schematically illustrated. Advantages and disadvantages are pointed out and individualization of operations is advised.
