What the trial is, and whether it could suit you
When controlling for tumor present in the Sentinel lymph node (SLN), intranodal hypoxia, as measured by Carbonic Anhydrase IX (CAIX IHC), is associated with worse PFS. This suggests that melanoma tumors may be utilizing deregulated metabolism as a means of propagating themselves to the next station of metastasis. This study aims to prospectively validate previous findings. Patients who are to undergo WLE and SLNB per standard of care (SOC) will be evaluable. It is hypothesized that SLN(s) with increased hypoxia, as measured by pimonidazole staining, will be associated with worse Progression-free Survival (PFS).

๐ Eligibility rules (as published)
Inclusion Criteria:
1. Must be willing and able to provide written informed consent for the study.
2. Must have histologically confirmed melanoma for which a Sentinel Lymph Node Biopsy (SLNB) is indicated per the treating physician.
3. Cutaneous or mucosal melanoma is permitted.
4. Female patients of childbearing potential must have a negative urine or serum pregnancy test within 7 days from the time of pimonidazole administration.
1. Female subjects of childbearing potential must not be pregnant or breastfeeding. Female subjects will be considered of non-reproductive potential if they:
1. are postmenopausal (defined as at least 12 months with no menses without an alternative medical cause; in women \< 45 years of age a high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. In the absence of 12 months of amenorrhea, a single FSH measurement is insufficient.
2. have had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy or bilateral tubal ligation/occlusion, at least 6 weeks prior to screening.
3. have a congenital or acquired condition that prevents childbearing.
2. Female and male subjects of reproductive potential must agree to avoid becoming pregnant or impregnating a partner, respectively, while receiving study drug and 1 week after the dose of study drug for females and 2 weeks for males by complying with one of the following:
1. practice abstinence from heterosexual activity
2. use (or have their partner use) acceptable contraception during heterosexual activity.
5. Adequate hematologic function: white blood cells (WBC) โฅ 2,500/ฮผL, platelet count โฅ 100,000/ฮผL, hemoglobin โฅ 8.0 g/dL
6. Adequate renal function: serum creatinine โค 2.0 mg/dL
7. Adequate hepatic function: serum alkaline phosphatase, bilirubin, and ALT โค twice the institutional upper limit of normal
Exclusion Criteria:
1. Subjects with known chronic immunosuppression (such as biologic agents like infliximab, mycophenolate, methotrexate, prednisone \> 20 mg daily).
2. Severe septicemia or severe infection in the 4 weeks prior to study entry.
3. History of previous neuropathy from chemotherapy or other causes not related to cancer.
4. Pregnant subjects or breastfeeding subjects. (Note: A pregnancy test will be administered within 7 days prior to the administration of pimonidazole to female subjects of childbearing potential enrolled in the study.)
5. Subjects with (ECOG) Performance scale of 4 - subjects unable to perform self-care.
6. Subjects who have received an investigational new drug 6 half-lives or two weeks prior to enrollment in this study, whichever is shorter.
