The incidence and prevalence of lip and oral cavity cancer has increased over the last decade, worldwide and in India. It ranks at 1st position in males in india, all ages, in 2020. Lips are essential organ of the body which carries dynamic role in facial expression, speech, sensuality, deglutition. Resection of central, large, lower lip cancer creates a more than 2/3rd large defect. Covering of this defect with maintenance of oral competency is a difficult task for a treating surgeon. Number of techniques are described for covering of large lower lip defects. Out of these techniques, karapandzic flap is a successful, accepted, simple, easy to learn reconstructive procedure with good cosmetic results. It is a modification of Gillie’s fan flap and it involves unilateral or bilateral full-thickness circumoral advancement-rotation flaps. The feature which distinguishes it from other techniques is preservation of neuro-vascular integrity, symmetry and oral competency. We are reporting a case of an elderly gentleman with large, central, lower lip cancer who underwent oncological resection with reconstruction by karapandzic flap technique.

Background: Actinic cheilitis, herpes labialis and lip cancer are relatively common conditions presenting on the lips associated with exposure to periods of sun exposure and thereby ultraviolet radiation. Objective: This systematic review aimed to determine the efficacy of the application of sunscreen-containing lip-protecting agents (LPA) in the prevention of actinic cheilitis (AC), recurrent herpes labialis (RHL) and lip cancer (LC). Methods: This review was conducted in accordance with the PRISMA guidelines and registered with the PROSPERO database. A literature search was conducted using SCOPUS, Google Scholar, Medline (Ovid), Pubmed, CINAHL, Cochrane Library databases and manual search using search terms actinic cheilitis (AC), recurrent herpes labialis (RHL) and lip cancer (LC) along with lip protecting agents and their variations as keywords. A total of 1,567 papers were yielded. Of them, nine studies were eligible for qualitative data synthesis. Results: Nine articles (3 AC, 5 RHL, 1 LC) were deemed eligible and thus selected for qualitative synthesis. Three studies on AC identified approximately 21.7% lower prevalence of lesions when some form of lip protection was used. Eighty percent of studies on RHL identified that the application of LPA is effective in preventing RHL. Subjects who applied LPA more than once daily only had half the risk of having LC compared to those who applied once daily. Conclusion: This review of randomised controlled trials (RCTs) and observational studies supports the use of LPA as an effective method in preventing lip-associated lesions. Further, RCTs and observational studies should aim at determining a definitive LPA application regime and optimal SPF strength to prevent lip-associated lesions. This systematic review was registered with the International Prospective Register of Systematic Reviews (PROSPERO): Registration Number - CRD42020177484. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020177484

Background Agricultural workers may be exposed to potential carcinogens including pesticides, sensitizing agents and solar radiation. Previous studies indicate increased risks of hematopoietic cancers and decreased risks at other sites, possibly due to differences in lifestyle or risk behaviours. We present findings from CanCHEC (Canadian Census Health and Environment Cohort), the largest national population-based cohort of agricultural workers. Methods Statistics Canada created the cohort using deterministic and probabilistic linkage of the 1991 Canadian Long Form Census to National Cancer Registry records for 1992–2010. Self-reported occupations were coded using the Standard Occupational Classification (1991) system. Analyses were restricted to employed persons aged 25–74 years at baseline (N = 2,051,315), with follow-up until December 31, 2010. Hazard ratios (HR) and 95% confidence intervals (CI) were modeled using Cox proportional hazards for all workers in agricultural occupations (n = 70,570; 70.8% male), stratified by sex, and adjusted for age at cohort entry, province of residence, and highest level of education. Results A total of 9515 incident cancer cases (7295 in males) occurred in agricultural workers. Among men, increased risks were observed for non-Hodgkin lymphoma (HR = 1.10, 95% CI = 1.00–1.21), prostate (HR = 1.11, 95% CI = 1.06–1.16), melanoma (HR = 1.15, 95% CI = 1.02–1.31), and lip cancer (HR = 2.14, 95% CI = 1.70–2.70). Decreased risks in males were observed for lung, larynx, and liver cancers. Among female agricultural workers there was an increased risk of pancreatic cancer (HR = 1.36, 95% CI = 1.07–1.72). Increased risks of melanoma (HR = 1.79, 95% CI = 1.17–2.73), leukemia (HR = 2.01, 95% CI = 1.24–3.25) and multiple myeloma (HR = 2.25, 95% CI = 1.16–4.37) were observed in a subset of female crop farmers. Conclusions Exposure to pesticides may have contributed to increased risks of hematopoietic cancers, while increased risks of lip cancer and melanoma may be attributed to sun exposure. The array of decreased risks suggests reduced smoking and alcohol consumption in this occupational group compared to the general population.
