Clinical case study analysis about the pathophysiology of basal cell carcinoma.

Introduction to the case: Ms. Jones is a 52 year old female farm worker that came into see her PCP with concerns of a lesion on the upper right side of her forehead. Ms. Jones is a fair skin lady with chronic sun exposure and a history of mutated PCTH1 gene. The patient noticed a small, pearly bump on her forehead that did not heal and continued to grow over several months. She reported occasional bleeding, itching and tenderness to the touch. After her first check check-up and biopsy, the results were positive for Basal Cell Carcinoma. Ms. Jones has been scheduled for surgical procedure to remove the tumor followed by radiation therapy. ​

Background detail: Due to the patients work she has been exposed to years of direct UV rays from the sun as well as sunburns. This along with her age, gender, are all contributing factors to her development of basal carcinoma.

Due to Ms. Jones’ history of being chronically exposed to sunlight, as well as the mutated MCTH1 gene, basal cell carcinoma is the most likely culprit since the mutated gene and exposure to ultraviolet radiation greatly increases the risk. Contributing to this is the fact that “basal-cell carcinoma is the most common malignant tumor, and its incidence is increasing” (Rubin 2005), especially given Ms. Jones’ age and fair skin.​

Pathophysiology: Basal cell carcinoma (BCC) mostly arises on sun-damaged skin and rarely develops on mucus membranes or palms and soles.​

• It occurs on the head or neck in the majority of cases, but can involve trunk and extremities.​
• Of note, the gene most often altered in BCC is the PTCH1 gene. PCTH1 gene mutations occur in 70% of people with sporadic BCC.​
• The second most common mutation found in BCC is the P53 gene.​
• The mechanism for BCC formation via UV radiation is direct DNA damage, indirect DNA damage, and immune suppression.​

Clinical assessment: Basal cell carcinoma is most often treated with surgery to remove all of the cancer and some of the healthy tissue around it. Options might include: Surgical excision; in this procedure, your doctor cuts out the cancerous lesions and a surrounding margin of healthy skin( Saldanha, et al, 2003).

Tests reveal that Ms. Jones has excessive levels of vitamin D, with a measurement of 150ng/ml, which can lead to clinical manifestations like Muscle weakness, Confusion, Appetite loss​, Dehydration​, Vomiting, Nausea​, Increased urination, and development of kidney stones​. Further checkup and biopsy reveals she is positive for Basal Cell Carcinoma​

Provide detailed answers to the following

• What are four medical-based evidence and/or research recommendations for the patient based on the assessment?
• Application to future practice: How can this theory be applied to future cases one may encounter in nursing?
• Please direct me to scholarly references supporting these ideas

ANSWER

Basal Cell Carcinoma: Medical-Based Evidence and Recommendations

Basal Cell Carcinoma (BCC) is a prevalent skin cancer that arises from the basal cells of the epidermis and is strongly associated with chronic sun exposure and genetic predisposition. Ms. Jones’ case highlights the importance of understanding the pathophysiology of BCC, its risk factors, and evidence-based recommendations for management.

Medical-Based Evidence and Recommendations

Early Detection and Biopsy: Regular skin examinations and early detection are crucial in cases like Ms. Jones’, where chronic sun exposure and genetic mutations increase the risk. Evidence suggests that regular skin examinations and prompt biopsy of suspicious lesions can lead to early diagnosis and improved outcomes (Kim et al., 2019). This emphasizes the importance of educating patients about self-examination and regular check-ups.

Surgical Excision with Margin Control: Surgical excision remains the primary treatment for BCC. Evidence supports the efficacy of surgical excision with a margin of healthy tissue to ensure complete tumor removal (Saldanha et al., 2003). Dermatologists and surgeons should adhere to established guidelines for optimal surgical margins to minimize the risk of recurrence.

Genetic Counseling and Testing: Considering Ms. Jones’ positive family history of mutated PTCH1 gene, genetic counseling and testing should be considered. Evidence shows that genetic counseling can help patients understand their risk factors, make informed decisions, and consider preventive strategies (Vysniauskaite et al., 2019). Genetic testing can identify individuals at risk and guide personalized management plans.

Sun Protection and Counseling: Education on sun protection measures is vital for patients at risk for BCC. Evidence-based recommendations emphasize the use of sunscreen, protective clothing, and sun avoidance during peak hours (Gallagher et al., 2017). Nurse practitioners should provide comprehensive counseling to encourage adherence to sun protection strategies.

Application to Future Practice

The insights gained from Ms. Jones’ case can be applied to future nursing practice in several ways:

Patient Education: Nurse practitioners can educate patients about the importance of regular skin self-examinations, early detection, and seeking medical attention for suspicious lesions. This proactive approach can contribute to early diagnosis and improved outcomes.

Genetic Risk Assessment: Incorporating genetic risk assessment and counseling into nursing practice can help identify individuals with a genetic predisposition to BCC. Nurses can collaborate with genetic counselors to provide personalized recommendations and support.

Promoting Sun Protection: Nurses play a pivotal role in promoting sun protection measures through patient education. They can emphasize the significance of sunscreen application, protective clothing, and avoiding excessive sun exposure to reduce the risk of BCC.

Multidisciplinary Collaboration: Ms. Jones’ case underscores the importance of multidisciplinary collaboration between nurses, dermatologists, surgeons, and genetic counselors. Collaborative efforts ensure comprehensive patient care, genetic risk assessment, and optimal treatment strategies.
