Basal cell carcinoma of the head and neck region: an analysis of 171 cases

Factors Influencing Margin Clearance and the Number of Stages of Mohs Micrographic Surgery in Basal Cell Carcinoma: A Retrospective Chart Review

How patient and tumor factors influence clearance margins and the number of Mohs Micrographic Surgery (MMS) stages when treating basal cell carcinoma (BCC) remains widely uncharacterized. It is important to elucidate these relationships, as surgical outcomes may be compared nationally between colleagues. Our objective is to evaluate the relationships between defect size and patient demographics, as well as between BCC subtypes and the number of MMS stages. Our second objective is to compare practice patterns and characteristics of patients requiring MMS at academic centers and private practices. A retrospective chart review was performed using data collected at academic centers (2015-2018) and private practices (2011-2018) of BCC patients older than 18 years old who underwent MMS. In total, 7651 patients with BCC requiring MMS were identified. Academic center adjusted analyses demonstrated clearance margins 0.1 mm higher for every year's increase in age (p < 0.0001) and 0.25 increase in MMS stages for high-risk BCC (p < 0.0001). Private practice adjusted analyses demonstrated clearance margins 0.04 mm higher for every year's increase in age (p < 0.0001). Clearance margins correlate with older age, and additional MMS stages correlate with high-risk BCC, suggesting the role patient and tumor factors may play in predicting tumor clearance and MMS stages.

Aesthetic Reconstruction Based on Facial Subunit Principle for Basal Cell Carcinoma of the Face: A Retrospective Analysis

Background and objective Basal cell carcinoma (BCC) is the most common malignancy of the skin. Reconstruction of post-excisional defects in BCC should follow the subunit principle for better outcomes. The location of BCC of the face is determined based on facial units; however, very few studies have described the involvement of multiple units and multiple subunits in BCC. In this study, we aimed to provide valuable insights into the management of BCC involving various facial units and subunits, thereby contributing to improved patient care and outcomes. Materials and methods We conducted a retrospective study at the Plastic Surgery Department of the SCB Medical College in Cuttack, Odisha, from January 2020 to January 2022, after obtaining ethical approval from the SCB Medical College IRB (no: 1155). We examined 35 patients with BCC of the face. The inclusion criteria were as follows: patients with early-stage and primary tumors that were mobile, not attached to underlying bone or cartilage, and amenable to surgical resection. Conversely, patients with late-stage, neglected, and recurrent tumors, fixed tumors, or those infiltrating the underlying bone or cartilage were excluded from the study. Data collection involved retrieving pertinent information from medical records, including parameters such as age, sex, tumor site, type of flap utilized, follow-up, and any complications observed. The tumor sites were further divided into six separate groups based on facial aesthetic units: the forehead, the nose, the area around the eyes, the cheek, the mouth, and the area around the ear, each with its own subunits. Results A total of 35 patients were included in this study, comprising 15 males (42.85%) and 20 females (57.15%), with a male-to-female ratio of 1:1.33. The ages of the patients ranged from 42 to 68 years. Among the facial units, the nose was the most commonly involved (in seven cases), while the lip was the least commonly affected (in one case). In 24 cases, a single unit was involved, while 11 cases involved multiple units. Furthermore, single subunits were affected in 18 cases, double subunits in 10 cases, three subunits in five cases, four subunits in one case, and five subunits in another case. Notably, no cases exhibited flap necrosis, wound dehiscence, wound hematoma, or seroma, indicating excellent surgical outcomes. All flaps remained viable, and all patients were followed up for a minimum of one year, with no reported recurrence during the follow-up period ranging from 6 to 18 months, reaffirming the effectiveness of the treatment approach. Conclusions For small, superficial lesions, full-thickness skin grafts (FTSG) are a suitable treatment option. However, when dealing with larger lesions that encompass multiple subunits, the preferred approach involves reconstructing with locoregional flaps. It is essential to plan the procedure carefully, taking into account the goal of positioning the final scar along the junction of facial subunits. This strategic plan aims to achieve superior aesthetic outcomes.

Recurrent nasal basal cell carcinoma treated with standard surgery excision: evaluation of volume ratio

BACKGROUND

Basal cell carcinoma (BCC) is the most common malignant skin tumor. Although it rarely evolves into a metastatic disease, BCC can lead to a significant morbidity due to local invasion. The risk of lesion recurrence depends on clinical and histopathological factors as described by the Nation Comprehensive Cancer Network (NCCN). The surgical excision margins have a well-known role: there is a close relationship between high recurrence rate of BCC and the tumor proximity to the surgical margins. Aim of our study was to assess whether there is a significative correlation between recurring BCC and volume ratio (VRb/t), defined as ratio between excisional biopsy volume and tumor volume, and if VRb/t is a useful parameter to assess the risk of recurrence of BCC.

METHODS

Retrospective case-control study in 80 patients with history of recurrent basal cell carcinoma of the nose (cases), and 43 patients with history of basal cell carcinoma of the nose with no evidence of relapse (controls) in the following 8 years.

RESULTS

Surgical excision margins, histological subtype, ulceration, depth of invasion and volume ratio (VRb/t) were evaluated in case and controls. The evaluation of VRb/t evidenced a significant difference between recurrent BCC and non-recurrent BCC. The mean values of VRb/t were 6.17 for cases and 11.94 for controls. The Binomial Logistic Regression has displayed, for values of VRb/t around 7, a probability of 75% to identify BCCs belonging to the recurrent group.

CONCLUSIONS

Our data show a significant correlation between recurrent BCCs and VRb/t. VRb/t can help in the assessment of recurrence risk, used together with others prognostic factor. For values of VRb/t close to 7 it should be recommended a close follow-up to promptly identify a possible recurrence.

Local Random Pattern and Axial Flaps for Reconstruction of Nasal Surgical Defects: Retrospective Analysis with an Attempt to Inspire ENT Surgeons

Aim: Reconstruction of the surgical defects of the external nose has been challenging and largely considered to be the domain of plastic reconstructive surgeons. The present study aims to share our experience in reconstructing such defects. Materials and methods: A retrospective analysis of 11 patients who underwent external nasal reconstruction secondary to surgical defect at our otolaryngology department in a tertiary care hospital from 2017 to 2019 was done. All the patients underwent surgical excision of a part of the external nasal dorsum followed by reconstruction by our team of otolaryngology surgeons using local random pattern/ axial flaps. The patients were followed up postoperatively for a period ranging from 3 months (for benign pathologies) to 2 years (malignant pathologies). Results: The flaps were taken up in all the patients. Minor complications like postoperative infection were seen in 2 cases, resulting in wound dehiscence in one that required resuturing that was uneventful. The appearance was bulky in all the patients, although the patients were satisfied with the overall cosmetic appearance. The average hospital stay was 2 to 4 days. Conclusion: Reconstruction of external nasal surgical defects is a challenging task. Thorough knowledge of relevant anatomy, proper planning, and availability of abundant vascularized donor tissue in the near vicinity of the defect makes this challenge acceptable with good outcomes even in the hands of otolaryngologists.

Correlation of basal cell carcinoma subtype with histologically confirmed subclinical extension during Mohs micrographic surgery: A prospective multicenter study

BACKGROUND

Traditionally "aggressive" histologic subtypes (HSs) of basal cell carcinoma (BCC) are more likely to quantitatively exhibit subclinical extension (SCE), requiring more stages during Mohs micrographic surgery (MMS) and, therefore, larger margins upon excision. However, the tendency for SCE has never been compared between HSs of BCC in a prospective manner.

OBJECTIVE

To prospectively correlate the HS of BCC with the likelihood of SCE as defined by the number of MMS stages required to clear the tumor.

METHODS

In a prospective, multicenter study involving 17 Mohs surgeons in 16 different practices across the United States, data regarding 1686 cases of BCC undergoing MMS were collected. Patient demographics, tumor characteristics, number of MMS stages required for tumor clearance, and specific BCC subtypes noted on both index biopsy and the final MMS stage were recorded.

RESULTS

Analysis of the average number of MMS stages for each HS required to clear tumor revealed 2 distinct degrees of SCE (P < .0001): high (higher than average) risk of SCE (1.9 stages, 1.0 SD) and low (lower than average) risk of SCE (1.6 stages, 0.9 SD). Subtypes of BCC within the high category were morpheaform (2.1), infiltrative (1.9), metatypical (1.9), mixed (1.8), and superficial (1.8). The low category included BCC subtypes of basosquamous (1.6), micronodular (1.6), nodular (1.6), and unspecified (1.5). Three hundred twenty-four cases (22.0%) manifested HS drift or a change in subtype from index biopsy to the final MMS stage. Superficial BCC was the only subtype that showed an increase in prevalence from index biopsy to the final MMS stage (from 16.0% to 25.8%; P < .0002).

LIMITATIONS

HSs from index biopsy may not be representative of all HSs present, resulting in sampling bias.

CONCLUSION

SCE of superficial BCC was as likely as SCE of BCC subtypes that are considered "aggressive" and are deemed "appropriate" for MMS by the appropriate use criteria. Our study also found that when HS drift occurs, the most likely subtype to extend subclinically is superficial BCC.

Facial Basal Cell Carcinoma: A Study of Causative Factors and Site-based Algorithm for Surgical Reconstruction

Background

Basal cell carcinoma (BCC) can be categorized as one of the commonly occurring skin malignancies in the world, with several variations in treatment protocols. Sun exposure has been attributed to its causality; however, other factors such as gender, age, and occupation also affect its incidence. We aimed to characterize the patient population who underwent surgical management for facial BCC at a tertiary referral hospital. Further, we have described an algorithm that may aid in surgical decision-making based on the location of the lesions on the face.

Materials and Methods

We performed a retrospective chart review of all patients who presented with a facial BCC to our institution between 2018 and 2019. Data regarding patients' demographic characteristics, skin phototype, average sun exposure, occupation, residence place (rural or urban), and surgical outcomes were recorded.

Results

Sixty-eight patients underwent reconstructive procedures after oncologic resection of facial BCC: 41.2% were males and 58.8% were females. Forty-eight (70.6%) patients were from rural areas, and 20 patients (29.4%) from urban areas (P < 0.001). Twenty-six patients reported >2 h of sunlight exposure, 16 reported <2 h of continuous sun exposure, and 26 reported intermittent sun exposure. A significantly higher proportion of patients with facial BCC presented with a Fitzpatrick skin type 4 in comparison to types 3 and 5 (P < 0.001). The most common reconstructive technique was the V-Y advancement flap (n=22, 32.4%), followed by the forehead flap (n=12, 17.6%) and the Limberg flap (n=12, 17.6%). All the flaps were healthy post-operatively and none of them suffered from flap failure, infection, or suture line dehiscence. There was no recurrence at 1-year follow-up.

Conclusion

This study gives a correlation between incidence of BCC and age, gender, and sun exposure in Indian population. In our experience, local flaps yield outstanding results and are the first choice for reconstruction of the face when composite defects are not present. Our algorithm aids in surgical decision-making.

Comparison of Demographic and Clinicopathological Characteristics of Basal Cell Carcinoma on the Nose and Other Sites of the Face: A Cross-Sectional Study

Introduction:

The clinicopathological characteristics of basal cell carcinoma (BCC) in different areas of the face, including the nose, are important and may be different. Accurate recognition of these characteristics may be necessary for the planning and selection of appropriate treatment.

Materials and Methods:

This cross-sectional study was conducted on 328 patients (131 females and 197 males) with 371 documented facial BCC in the West of Iran within 2013-2018. The demographic and clinicopathological data of the patients in the nose area were compared with other sites of the face by appropriate statistical methods.

Results:

Out of 371 lesions, 38.8% of the cases were on the nose, 75.8% were primary lesions, 97.8% had no perineural invasion, 89.2% were nodular, and 65.8% were of nodular clinical and pathologic type, which were the most common variables of patients. It was revealed that early-onset (P<0.001), smaller size (P<0.001), high-risk pathologic type (P=0.01), and recurrent lesions (P=0.013) were significantly higher in the nasal BCC. However, there was no significant difference between BCC in the nose and other sites of the face in terms of gender (P=0.654), high-risk clinical type (P=0.06), and perineural invasion (P=0.275).

Conclusion:

Considering the nasal site as an important cosmetic unit, more limitation of the nose in performing any procedure, and presence of the more risk factors in the nose than in other areas of the face, the definite treatment of nasal BCC requires special attention, expertise, and experience.

Evaluation of skin cancer resection guide using hyper-realistic in-vitro phantom fabricated by 3D printing

Skin cancer usually occurs in the facial area relatively exposed to sunlight. Medical imaging can confirm the invasiveness and metastasis of skin cancer, which is used to establish a surgical plan. However, there is no method of directly marking this information on the patient's skin in the operating room. We evaluated a skin cancer resection guide that marks resection areas including safety margins on the patient's skin based on medical images and in-vitro phantom fabricated via 3D printing. The in-vitro phantom, which includes the skull, skin, and five different cancer locations was designed and fabricated based on a CT image of a patient. Skin cancer resection guides were designed using a CT image of an in-vitro phantom, with a safety margin, and four injection points at each cancer. The guide was used to insert 16 cc intravenous catheters into each cancer of the phantom, which was rescanned by CT. The catheter insertion point and angle were evaluated. The accuracy of the insertion points was 2.09 ± 1.06 mm and cosine similarities was 0.980 ± 0.020. In conclusion, skin cancer resection guides were fabricated to mark surgical plans on the patient's skin in the operating room. They demonstrated reasonable accuracies in actual clinical settings.

Incomplete surgical excision of keratinocyte skin cancers: a systematic review and meta‐analysis*

BACKGROUND

Keratinocyte or nonmelanoma skin cancer (NMSC) is the commonest malignancy worldwide. The usual treatment is surgical excision. Current guidelines underestimate incomplete excision rates.

OBJECTIVES

We aimed to determine the risk of incomplete excision of NMSCs through a systematic review and meta-analysis of primary clinical studies.

METHODS

A PRISMA-compliant systematic review and meta-analysis was performed using methodology proposed by Cochrane (PROSPERO CRD42019157936). A comprehensive search strategy was applied to MEDLINE, Embase, Scopus, CINAHL, EMCare, Cochrane Library and the grey literature (January 2000-27 November 2019). All studies were included except those on Mohs micrographic surgery, frozen section or biopsies. Abstract screening and data extraction were performed in duplicate. Risk of bias was assessed using a tool for prevalence/incidence studies. The primary outcome was the proportion of incomplete surgical excisions. A random-effects model for pooling of binomial data was used. Differences between proportions were assessed by subgroup meta-analysis and meta-regression, which were presented as risk ratios (RRs).

RESULTS

Searching identified 3477 records, with 110 studies included, comprising 53 796 patients with 106 832 basal cell carcinomas (BCCs) and 21 569 squamous cell carcinomas (SCCs). The proportion of incomplete excisions for BCC was 11·0% [95% confidence interval (CI) 9·7-12·4] and for SCC 9·4% (95% CI 7·6-11·4). Proportions of incomplete excisions by specialty were: dermatology, BCCs 6·2% and SCCs 4·7%; plastic surgery, BCCs 9·4% and SCCs 8·2%; general practitioners, BCCs 20·4% and SCCs 18·9%. The risk of incomplete excision for general practitioners was four times that of dermatologists for both BCCs (RR 3·9, 95% CI 2·0-7·3) and SCCs (RR 4·8, 95% CI 1·0-22·8). Studies were heterogeneous (I²  = 98%) and at high risk of bias.

CONCLUSIONS

The proportion of incomplete excisions is higher than previously reported. Excisions performed by specialists may lower the risk of incomplete excision.

Magnetic Resonance Imaging Findings Differentiating Cutaneous Basal Cell Carcinoma from Squamous Cell Carcinoma in the Head and Neck Region

Objective

This study aimed to evaluate the efficacy of magnetic resonance (MR) imaging in differentiating between cutaneous basal cell carcinoma (cBCC) and cutaneous squamous cell carcinoma (cSCC) in the head and neck region.

Materials and Methods

Among patients with cutaneous head and neck cancers, 14 with primary cBCCs and 15 with primary cSCCs with a histologic tumor height of ≥ 4 mm underwent MR examinations; the findings were then examined for correlations.

Results

cBCCs (71%) occurred more frequently on the nose than cSCCs (13%) (p < 0.01). The maximum diameter (23.5 ± 7.2 mm vs. 12.7 ± 4.5 mm; p < 0.01) and diameter-to-height ratio (2.8 ± 0.9 vs. 1.7 ± 0.4; p < 0.01) were significantly greater in cSCCs than in cBCCs. Superficial ulcer formation (67% vs. 21%; p < 0.05), protrusion into the subcutaneous tissue (60% vs. 21%; p < 0.05), ill-demarcated deep tumor margins (60% vs. 7%; p < 0.01), and peritumoral fat stranding (93% vs. 7%; p < 0.01) were more frequently observed in cSCCs than in cBCCs. Intratumoral T2-hyperintense foci (57% vs. 13%; p < 0.05) were more frequently observed in cBCCs than in cSCCs.

Conclusion

cBCCs predominantly occurred on the nose with intratumoral T2-hyperintense foci, whereas cSCCs predominantly exhibited a flattened configuration, superficial ulcer formation, protrusion into the subcutaneous tissue, ill-demarcated deep tumor margin, and peritumoral fat stranding.

Treatment and Outcomes for Cutaneous Periauricular Basal Cell Carcinoma: A 16-Year Institutional Experience

Objective

To report a single institutional experience with the surgical management of cutaneous periauricular basal cell carcinoma.

Study Design

Retrospective chart review.

Setting

Tertiary academic center.

Methods

Retrospective chart review of 71 patients diagnosed with periauricular basal cell carcinoma managed surgically from 2000 to 2016. Data were analyzed with descriptive statistics.

Results

The median age at diagnosis was 73.0 years (interquartile range, 13.0). Of all lesions, 2.8% (n = 2) were preauricular, 80.3% (n = 57) auricular, and 16.9% (n=12) postauricular. Auricular subsites included conchal bowl (36.6%, n = 26), helix (21.1%, n = 15), antihelix (1.4%, n = 1), peritragus (5.6%, n = 4), triangular fossa (1.4%, n = 1), external auditory canal (2.8%, n = 2), and lobule skin (1.4%, n = 1). Surgical approach included wide local excision (80.3%, n = 57), partial auriculectomy (8.5%, n = 6), and total auriculectomy or other combinations of surgical methods (11.3%, n = 8). Due to aggressive pathology, 3 cases required concurrent parotidectomy, neck dissection, ear canal sleeve resection, or mastoidectomy. In sum, 52.1% (n = 37) of cases had clear margins on first pass in the operating room; 25.4% (n = 18) required further resection; and 12.7% (n = 9) demonstrated final positive/overturned margins read as negative from the frozen sections. Reconstruction included full-thickness (25.4%, n = 18) or superficial-thickness (29.6%, n = 21) skin grafts and local flap reconstruction (25.4%, n = 18), while 5.6% (n = 4) required combinations of free flap and/or other reconstruction techniques; 14.1% (n = 10) did not undergo formal reconstruction.

Conclusion

Periauricular basal cell carcinoma occurs in anatomically diverse locations in and around the ear, and multiple surgical methods are required for successful treatment.

Factors associated with incomplete surgical margins in basal cell carcinoma of the head and neck

Introduction

Cutaneous basal cell carcinoma recurrence is associated with inadequate surgical margins. The frequency of and the factors associated with compromised or inadequate surgical margins in head and neck basal cell carcinoma varies.

Objective

The purpose of this study was to evaluate the clinical and pathological factors associated with inadequate surgical margins in head and neck basal cell carcinoma.

Methods

We developed a cross-sectional study comprising all patients who had undergone resection of head and neck basal cell carcinoma from January 2017 to December 2019. Data on age, sex, head and neck topography, histopathological findings, and staging were retrieved and compared. Each tumor was considered an individual case. Compromised and close margins were termed “inadequate” or “incomplete”. Variables that were significantly associated with the presence of incomplete margins were further assessed by logistic regression.

Results

In total, 605 tumors from 389 patients were included. Overall, sixteen cases (2.6%) were classified as compromised, 52 (8.5%) as close, and 537 (88.7%) as free margins. Presence of scleroderma (p = 0.005), higher Clark level (p < 0.001), aggressive variants (p < 0.001), invasion beyond the adipose tissue (p < 0.001), higher T stage (p < 0.001), perineural invasion (p = 0.002), primary site (p = 0.04), multifocality (p = 0.01), and tumor diameter (p = 0.02) showed association with inadequate margins. After Logist regression, multifocality, Clark level and depth of invasion were found to be independent risk factors for inadequate margins.

Conclusion

Gross clinical examination may be sufficient for determining low prevalence of inadequate surgical margins when treating head and neck basal cell carcinoma in highly experienced oncologic centers. Multifocality, Clark level and depth of invasion were found to be independent risk factors for incomplete margins.

Outcome Study after Nasal Alar/Peri-alar Subunit Reconstruction: Comparing Paramedian Forehead Flap to Nasolabial Flap

Objective:

Contours of the lower nasal third are unique and present challenges in surgical reconstruction. The nasal alar intricate curved anatomy makes the area easily compromised after Mohs surgery. Managing patient and surgeon expectations with regard to aesthetics and functionality remains the reconstructive goal. The purpose of the study was to compare patients’ perspective on aesthetics and functional outcomes of nasal alar reconstruction post Mohs ablative surgery using nasolabial or forehead flaps.

Methods:

A single surgeon’s results of 23 patients, who underwent nasal alar reconstruction post Mohs surgery, were included for analysis (15 forehead and 8 nasolabial flaps). Initially, 103 consecutive patients undergoing nasal reconstruction were reviewed, with 67 excluded due to nonalar subunit involvement and an additional 13 excluded for other discussed reasons. Mean follow-up period was 2.3 years. Evaluation of a patient satisfaction questionnaire assessed aesthetics and functionality and also surgical scar noticeability. Additionally, 3 board-certified plastic surgeons assessed postoperative images.

Results:

Twenty-three patients completed the survey. There was no statistically significant difference in gender ratio, follow-up time, or scar noticeability among groups. A difference was noted in both aesthetics and functionality score (P < 0.03) for both variables favoring forehead flaps. Results from the surgeon’s questionnaire also confirmed the superiority of forehead flaps concerning scar, alar contour/symmetry, and nostril opening symmetry.

Conclusions:

The forehead flap has a better functional and aesthetic outcome and an overall superior level of satisfaction post Mohs ablative surgery.

Oncologic outcomes after surgery for locally aggressive basal cell carcinoma of the head and neck

OBJECTIVE

Although basal cell carcinoma (BCC) is the most common skin cancer, locally aggressive BCC of the head and neck is rare and not well studied.

STUDY DESIGN

Retrospective review of patients who underwent primary surgical resection of locally aggressive head and neck BCC at a single tertiary academic center.

RESULTS

Eighty-seven patients with 98 tumors demonstrated a 5-year Kaplan-Meier estimated recurrence-free survival of 64.5%, overall survival of 83.3%, and disease-specific survival of 98.3%. Intraoperative positive frozen section margin was a strong independent predictor of local recurrence (hazard ratio 6.88, P = 0.038) and was more likely to occur in tumors previously treated with radiation (odds ratio 6.47 = 0.05).

CONCLUSION

Locally aggressive BCCs of the head and neck have high rates of local recurrence but low disease-specific mortality when treated with primary surgery and selected use of adjuvant therapy. Intraoperative positive frozen section margin is a strong independent predictor of local recurrence and is more likely in tumors that were previously treated with radiation therapy.

Trends in basal cell carcinoma incidence rates: a 16-year retrospective study of a population in central Poland

Introduction

Basal cell carcinoma (BCC) is the most commonly occurring cancer worldwide, and the overall incidence is still rising. Unfortunately, the cancer registry in Poland does not record BCC individually. Thus, the incidence of BCC in a defined population is unknown.

Aim

Analysis of incidence rates of primary BCC in central Poland during 16 years considering sex, site distribution and age to determine trends.

Material and methods

We retrospectively included all cases of BCC which were diagnosed and treated in the Department of Dermatology and Venereology, Medical University of Lodz, during the 16-year period from 1999 to 2015.

Results

We recorded 945 BCCs occurring in 890 patients (504 females - 57%, 386 males - 43%). Patient's age was between 21 and 94. A distinct increase in BCC was observed after 1999, while after 2010 during the next 2-year period a slight decrease was noted. A statistically significant correlation was observed between histopathological types of BCC and the location of the lesions. The superficial type predominates on photoprotected areas, especially on the trunk, while the nodular type occurs mainly in facial areas. No statistically significant correlation was observed between histopathological types of BCC and sex. We found a significant increase in incidence for superficial BCC among middle-age patients, while the nodular type was observed more frequently among elderly subjects.

Conclusions

Basal cell carcinoma is quite common in Poland and predominantly develops in the facial area. In middle-age patients the most common is superficial BCC, while in elderly people the nodular type is most common. Based on our results we assume that there is a strong need to educate general physicians to enable them to diagnose BCC in the early stages.

Surgical treatment of nasal non-melanoma skin cancer in elderly patients using dermal substitute

CONCLUSIONS

The nose is often involved by non-melanoma skin cancer (NMSC) and the increase in the incidence of such tumors, the morbidity and treatment-related costs represent a significant burden to healthcare systems. A bioresorbable dermal substitute (Hyalomatrix^®) has been used for immediate dermal coverage and nose restoration after excision of infiltrating nasal NMSCs in elderly ASA III patients. Further studies on dermal substitutes are needed to improve benefit to patients.

OBJECTIVE

Surgical treatment of nasal non-melanoma skin cancer (NMSC) in elderly patients.

MATERIALS AND METHODS

Ten elderly ASA III patients with nasal defects after resection of infiltrating NMSC were reconstructed in a two-stage strategy. The surgical protocol targeted an initial wide tumor excision and apposition of a dermal induction template (Hyalomatrix^®) and successive full thickness skin autograft. Results were documented by photography, visual analog scale for patient satisfaction, and Vancouver scar scale for evaluation of final graft characteristics.

RESULTS

All patients were tumor-free during the 2 years follow-up. The procedure achieved acceptable nose reshaping and graft scarring evolution. Patient satisfaction was good-to-high.

Three-layer reconstruction of lower third nasal defects using forehead flap, reversed nasolabial flap, and auricular cartilage

The reconstruction of a full-thickness defect of the distal third of the nose requires the restoration of all three anatomical layers. A practical method for three-layer reconstruction of the lower third of the nose and the long-term results of this technique are presented herein. A combined reconstruction technique was utilized, including a reverse subcutaneous pedicled nasolabial flap to restore the nasal mucosa, an auricular cartilage graft for structural support, and a forehead flap for cutaneous coverage of the defect. This technique was applied in 21 patients following the full-thickness excision of basal cell carcinoma of the lower part of the nose. All patients (12 male and nine female; mean age 59.8 years) were treated successfully and were satisfied with the aesthetic and functional outcomes. The wound had to be further revised in three cases for the correction of contour or residual deformities; however, no further complications were experienced. One patient had a wound infection and the cartilage had to be removed. The grafting procedure was repeated successfully after resolution of the infection. Donor site morbidity was unremarkable. Combined flaps from the forehead and nasolabial regions with an incorporated auricular cartilage graft can be used to reconstruct full-thickness defects of the lower third of the nose.

Can dressings soaked with polyhexanide reduce bacterial loads in full-thickness skin grafting? A randomized controlled trial

BACKGROUND

Polyhexamethylene biguanide (PHMB)-based antiseptic solutions can reduce bacterial loads in different clinical settings and are believed to lower risk of infections.

OBJECTIVE

We sought to assess the efficacy of a PHMB-based solution in lowering bacterial loads of full-thickness skin grafting wounds and the risk of surgical site infections (SSIs).

METHODS

In this double-blinded clinical trial, 40 patients planned for facial full-thickness skin grafting were randomized 1:1 to receive tie-over dressings soaked with either PHMB-based solution or sterile water. Quantitative and qualitative bacterial analysis was performed on all wounds before surgery, at the end of surgery, and 7 days postoperatively. In addition, all patients were screened for nasal colonization of Staphylococcus aureus.

RESULTS

Analysis of wounds showed no statistically significant difference in bacterial reductions between the groups. The SSI rates were significantly higher in the intervention group (8/20) than in the control group (2/20) (P = .028). Higher postoperative bacterial loads were a common finding in SSIs (P = .011). This was more frequent when S aureus was present postoperatively (P = .034), intraoperatively (P = .03), and in patients with intranasal S aureus colonization (P = .007).

LIMITATIONS

Assessment of SSIs is largely subjective. In addition, this was a single-center study and the total number of participants was 40.

CONCLUSION

Soaking tie-over dressings with PHMB solution in full-thickness skin grafting had no effect on postoperative bacterial loads and increased the risk of SSI development. The presence of S aureus intranasally and in wounds preoperatively and postoperatively increased postoperative bacterial loads, which in turn resulted in significantly more SSIs.

A study of Basal cell carcinoma in South asians for risk factor and clinicopathological characterization: a hospital based study

Objectives. Although the incidence of skin cancers in India (part of South Asia) is low, the absolute number of cases may be significant due to large population. The existing literature on BCC in India is scant. So, this study was done focusing on its epidemiology, risk factors, and clinicopathological aspects. Methods. A hospital based cross-sectional study was conducted in Punjab, North India, from 2011 to 2013. History, examination and histopathological confirmation were done in all the patients visiting skin department with suspected lesions. Results. Out of 36 confirmed cases, 63.9% were females with mean ± SD age being 60.9 ± 14.2 years. Mean duration of disease was 4.7 years. Though there was statistically significant higher sun exposure in males compared to females (P value being 0.000), BCC was commoner in females, explainable by intermittent sun exposure (during household work in the open kitchens) in women. Majority of patients (88.9%) had a single lesion. Head and neck region was involved in 97.2% of cases, with nose being the commonest site (50%) with nodular/noduloulcerative morphology in 77.8% of cases. Pigmentation was evident in 22.2% of cases clinically. Nodular variety was the commonest histopathological variant (77.8%). Conclusions. This study highlights a paradoxically increasing trend of BCC with female preponderance, preferential involvement of nose, and higher percentage of pigmentation in Indians.

Analysis of selected recurrence risk factors after treatment of head and neck basal cell carcinoma

Introduction

Basal cell carcinoma (BCC) is the most common type of non-melanoma malignant skin tumors. Eighty-five percent of all cases are located on the skin of the head and neck. The risk of recurrence after surgery is estimated at 5–15%.

Aim

To evaluate the selected risk factors for recurrence after surgical treatment of head and neck BCC at the Department of Head and Neck Surgery in the Greater Poland Cancer Centre of the Poznan University of Medical Sciences.

Material and methods

A retrospective analysis was made of patients treated at the Department of Head and Neck Surgery in the Greater Poland Cancer Centre of the Poznan University of Medical Sciences in 2007–2012 for BCC of the head and neck region. The study covered 312 patients: 198 males (63%) and 114 females (37%), aged 32–96 years.

Results

In the study group of 312 tumors, recurrence after initial treatment in this Centre was diagnosed in 18 patients (9%), whereas in patients who were previously operated elsewhere, recurrence was found in 22 cases (17%). The nodular type was the most common BCC type in the study group and concerned 175 patients (56%). The most numerous group (114; 37%) in this study group comprised patients with external nose and cheek tumors.

Conclusions

The importance of preoperative biopsy to assess the histological type as a routine treatment of patients with BCC is essential. Ultrasound evaluation to assess the exact size and depth of tumor invasion should also be implemented.

Basal cell carcinoma of the head and neck region: a retrospective analysis of completely excised 331 cases

The aim of the study is to analyze all completely excised BCCs in the head and neck region with regard to age, sex, personal and familial history, skin type, tumor localization and size, histopathological subtype of tumor, reconstruction method, and recurrence rates. Incompletely excised BCCs were not included in this study since incomplete excision is the most important preventable risk factor for recurrence. In 320 patients, 331 lesions were retrospectively evaluated by dividing into the following 8 subunits: scalp, frontotemporal, orbital, nose, cheek, auricula, perioral, and chin-neck area. Most of the patients were in 60-70 age group (34.7%). The nose (32.3%) was the most common site of presentation. Clinically, all lesions and, histopathologically, most of the lesions (42.2%) presented were of the nodular type. All cases of recurrence after complete excision (n = 9, 2.7%) were located in the median parts of the head and neck region and were mainly diagnosed histopathologically as sclerotic and micronodular. Even though completely excised, head and neck region BCCs, especially which are more prone to recurrence due to anatomical and histopathological properties, should be more closely monitored in order to decrease morbidity and health care costs.
