RESUMO

Disparities in outcomes exist in outcomes of coronavirus disease-19 (COVID-19). Little is known about other ethnic minorities in United States. We included all COVID-19 positive adult patients (≥18 years) hospitalized between March 1, 2020 and February 5th 2021. We compared in hospital mortality, use of intensive care unit services and inflammatory markers between non-Hispanic whites with non-White/Black Hispanic. Multivariable Cox proportional Hazard models were used to adjust for differences between the two groups. There were 4059 hospital admissions with COVID-19 in the study period. Of the 3288 White, 789 (24%) required intensive care unit (ICU) admission in comparison to 187 (24.3%) of the 770 Hispanics. Unadjusted mortality was higher in Whites than Hispanics (17.1% vs. 10.7%; p < 0.001). After adjusting for confounding variables, in-hospital mortality was not statistically different for Whites in comparison to Hispanics (hazard ratio [HR]: 0.96, 95% confidence interval [CI]: 0.76-1.21, p = 0.73). The adjusted rates of ICU transfers were significantly higher in Hispanics (HR: 1.34, 95% CI: 1.11-1.61, p = 0.002). Hispanics had significantly higher C-reactive protein, lactate dehydrogenase, and fibrinogen when compared to Whites. Hispanics as compared to Whites with COVID-19 require higher rates of ICU admission but have a similar mortality. Hispanics as compared to Whites with COVID-19 require higher rates of ICU admission but have a similar mortality.

RESUMO

Coronavirus disease 2019 (COVID-19) is characterized by dysregulated hyperimmune response and steroids have been shown to decrease mortality. However, whether higher dosing of steroids results in better outcomes has been debated. This was a retrospective observation of COVID-19 admissions between March 1, 2020, and March 10, 2021. Adult patients (≥18 years) who received more than 10 mg daily methylprednisolone equivalent dosing (MED) within the first 14 days were included. We excluded patients who were discharged or died within 7 days of admission. We compared the standard dose of steroids (<40 mg MED) versus the high dose of steroids (>40 mg MED). Inverse probability weighted regression adjustment (IPWRA) was used to examine whether higher dose steroids resulted in improved outcomes. The outcomes studied were in-hospital mortality, rate of acute kidney injury (AKI) requiring hemodialysis, invasive mechanical ventilation (IMV), hospital-associated infections (HAI), and readmissions. Of the 1379 patients meeting study criteria, 506 received less than 40 mg of MED (median dose 30 mg MED) and 873 received more than or equal to 40 mg of MED (median dose 78 mg MED). Unadjusted in-hospital mortality was higher in patients who received high-dose corticosteroids (40.7% vs. 18.6%, p < 0.001). On IPWRA, the use of high-dose corticosteroids was associated with higher odds of death (odds ratio [OR] 2.14; 95% confidence interval [CI] 1.45-3.14, p < 0.001) but not with the development of HAI, readmissions, or requirement of IMV. High-dose corticosteroids were associated with lower rates of AKI requiring hemodialysis (OR 0.33; 95% CI 0.18-0.63). In COVID-19, corticosteroids more than or equal to 40 mg MED were associated with higher in-hospital mortality.

RESUMO

OBJECTIVE: Severe sepsis requires timely management and has high mortality if care is delayed. Hematopoietic stem cell transplant recipients are more likely to be immunocompromised and are predisposed to serious infections. Reports of outcomes of severe sepsis in this population are limited to data from single, tertiary care centers, and national outcomes data are missing. DESIGN: Retrospective analysis of an administrative database. SETTING: Twenty percent of community hospitals in United States, excluding federal hospitals. SUBJECT: Patients with severe sepsis. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: We used International Classification of Diseases, 9th Edition, Clinical Modification codes indicating the presence of sepsis and organ system failure to identify hospitalizations for severe sepsis between 2000 and 2008. We also used International Classification of Diseases, 9th Edition, Clinical Modification codes to identify hematopoietic stem cell transplant recipients. We compared outcomes of hematopoietic stem cell transplant recipients with severe sepsis during engraftment and subsequent admissions with a non-hematopoietic stem cell transplant cohort and excluded solid-organ transplantation from this cohort. We used mixed effect, multivariate logistic regression modeling with propensity score adjustment to examine factors associated with mortality of severe sepsis in hematopoietic stem cell transplant recipients. A total of 21,898 hematopoietic stem cell transplant recipients with severe sepsis were identified. The frequency of severe sepsis in hematopoietic stem cell transplant recipients was five times higher when compared with the non-hematopoietic stem cell transplant cohort. The unadjusted mortality was 32.9% in non-hematopoietic stem cell transplant cohort, which was similar to autologous hematopoietic stem cell transplant recipients (30.1%) and those who did not develop graft-versus-host disease (35%). Mortality was significantly higher in allogeneic transplants (55.1%, p < 0.001) and in those who developed graft-versus-host disease (47.9%, p < 0.001). After adjustment, during engraftment admission, the odds of in-hospital mortality in allogeneic hematopoietic stem cell transplant (odds ratio, 3.81; 95% CI, 2.39-6.07) and autologous hematopoietic stem cell transplant (odds ratio, 1.28; 95% CI, 1.06-1.53) recipients was significantly higher than non-hematopoietic stem cell transplant patients. Similarly, in subsequent admissions, hematopoietic stem cell transplant recipients with graft-versus-host disease (odds ratio, 2.14; 95% CI, 1.88-2.45) and without graft-versus-host disease (odds ratio, 1.35; 95% CI, 1.19-1.54) had significantly higher odds of mortality than non-hematopoietic stem cell transplant patients. Among patients with hematopoietic stem cell transplant, persons with autologous hematopoietic stem cell transplant and those without graft-versus-host disease fared better as compared with their allogeneic and graft-versus-host disease counterparts. CONCLUSIONS: Hematopoietic stem cell transplant recipients are more likely to develop severe sepsis and die following a severe sepsis episode than nontransplant patients. Autologous hematopoietic stem cell transplant recipients and those who do not develop graft-versus-host disease have significantly better outcomes than allogeneic and graft-versus-host disease patients.

RESUMO

BACKGROUND: Phase 2 trials suggest that prolonged intravenous (IV) infusion of the topoisomerase 1 inhibitor topotecan may be less toxic than when given by standard IV bolus 5-day administration. Oxaliplatin exhibits efficacy in platinum-pretreated disease and shows preclinical synergy with topoisomerase 1 inhibitors. We sought to determine the efficacy and safety of oxaliplatin plus infusion topotecan in recurrent platinum-pretreated ovarian cancer. METHODS: Patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancers previously treated with 1 to 2 prior regimens including platinum and taxane received oxaliplatin (85 mg/m(2) day 1 and day 15) and topotecan (0.4 mg/m(2) per day) by continuous IV infusion over 14 days every 4 weeks. The primary objective of the trial was to estimate the objective response rate in platinum-resistant disease (stratum 1) and in platinum-sensitive disease (stratum 2). Toxicities were assessed in all patients. RESULTS: Thirty-eight patients received 144 cycles of therapy (median, 4; range, 1-6). The most common grade 3 and grade 4 toxicities included thrombocytopenia (grade 3, 37%; and grade 4, 19%), neutropenia (grade 3, 37%; grade 4, 11%), and anemia (grade 3, 15%). Response occurred in 4 of 19 patients in stratum I (21%; 95% confidence intervals, 6%-46%) and 9 of 19 patients in stratum 2 (47%; 95% CI, 24%-71%). Three in each stratum had lengthy complete responses. CONCLUSIONS: Biweekly oxaliplatin plus a 14-day continuous IV infusion of topotecan, given monthly, is an active regimen in platinum-pretreated ovarian cancer and merits additional evaluation.

RESUMO

Metastatic cancer can arise years after treatment of the primary tumor because residual tumor cells can enter dormancy and evade elimination by anti-neoplastic therapies. The mechanisms underlying this phenomenon have been investigated and a number of hypotheses have been proposed. Tumor mass dormancy involves a balance between apoptotic and proliferative cells, keeping a micrometastatic lesion constant in size. This induces a need for blood supply which involves angiogenic dormancy. Cellular dormancy is also considered a mechanism of dormancy, where dormancy is induced due to cells entering a quiescent, reversible, growth-arrested state. In addition to all of these mechanisms, important changes in the tumor microenvironment, including the extracellular matrix, the oxygenation levels of the environment, and endoplasmic reticulum stress, are involved in inducing and maintaining tumor dormancy. Since dormant tumors are commonly known to be resistant to chemotherapy, gaining more knowledge of the mechanism of dormant tumor cells is of importance, as it can lead to the development of future treatment strategies.

RESUMO

Background: The treatment of salivary gland tumors has not changed significantly in the past two decades. However, the increase in the geriatric population with these tumors poses a new challenge for their management. This study explores the incidence-based mortality trends in the geriatric and non-geriatric population for the time period of 2000 - 2014 and compares the trends between races. Methods: Mortality data were extracted from the Surveillance, Epidemiology, and End Results (SEER) Database for the years 2000 - 2014. Incidence-based mortality for all stages of salivary gland tumors was queried and the results were grouped by age (geriatric vs. non-geriatric determined as 65 vs. below 65 years of age) and race (Caucasian/White, African American/Black, American Indian/Alaskan native and Asian/Pacific Islander). All stages and both genders were included in the analysis. T-test was used to determine statistically significant difference between various subgroups. Linearized trend lines were used to visualize the mortality trends between various subgroups (geriatric vs. non-geriatric and Caucasian vs. African American). Results: Incidence-based mortality for salivary gland tumors has worsened since 2000 to 2014 for both geriatric and non-geriatric patients (P < 0.05). There was a statistically significant difference between these two groups in both Caucasian/White patients and African American/Black patients. Notably, the worst incidence-based mortality rates were noted in African American/Black non-geriatric patients followed by Caucasian/White non-geriatric patients. However, there was no statistical difference in incidence-based mortality between Caucasian/White patients and African American/Black geriatric patients. Conclusions: The similarity in incidence-based mortality for geriatric patients with salivary gland tumors in both Caucasian/White patients and African American/Black groups suggests that the effects of race may not be pronounced in the elderly population. The high rate of incidence-based mortality in African American/Black non-geriatric patients may suggest environmental influence and warrants further study.

RESUMO

Mucoepidermoid carcinoma (MEC) represents 10-15% of salivary neoplasms. Due to their low incidence, it is challenging to conduct clinical trials and develop treatment guidelines. Although surgery is the most common approach for a resectable tumor, various treatment options such as chemotherapy, radiotherapy, and immunotherapy have been investigated. There is a need to implement a standardized treatment protocol to effectively manage MEC as it is a common histological subtype. Furthermore, it has become essential to assess chromosomal and genetic abnormalities recently identified with MEC, including alterations of CDKN2A, TP53, CDKN2B, BAP1, etc. These mutations are involved in the transformation of low-grade tumors to high-grade tumors, presenting a vital tool for evaluating the aggressive behavior of this carcinoma. Detailed immunohistochemical and translocation studies can help develop targeted therapies and monitor treatment response. Therefore, biomarker-driven research will immensely improve the outcome, especially in advanced cases. Based on thorough histology and chromosomal translocations, a more personalized treatment plan can improve the overall disease outcome. The purpose of this article is to elaborate on the current treatment advancements, particularly chemotherapy and targeted therapy, as an effective treatment modality for the management of MEC and highlight the comparison with traditional treatment approaches.

RESUMO

Small cell lung cancer (SCLC) is a smoker's disease and occurs almost exclusively in smokers. SCLC is a high-grade neuroendocrine tumor and commonly presents as a central tumor with bulky mediastinal adenopathy. It is notorious for causing widespread disease and paraneoplastic syndromes. The usual sites of metastasis include the liver, brain, bone, and adrenals. SCLC presenting with breast metastasis is unusual; however, there are reports of unilateral and bilateral breast metastases. SCLC with bilateral breast metastases is extremely rare, with only five previously reported cases available in the literature. We are taking this opportunity to report and add to the growing literature on the unusual presentation of a small cell lung cancer with bilateral breast metastases.

RESUMO

Hyponatremia, a serum sodium level of <135 mEq/L, is the most common electrolyte abnormality occurring in 5%-35% of hospitalized patients. It is a predictor of increased morbidity and mortality. Diuretics, psychotropic, and antiepileptic drugs are commonly implicated in drug-induced hyponatremia. Trimethoprim-sulfamethoxazole and spironolactone are two commonly prescribed drugs; unfortunately, most providers are unfamiliar with these two drugs causing hyponatremia. Simultaneous use of trimethoprim-sulfamethoxazole and spironolactone can cause serious drug interactions that increase the risk of hyponatremia, hyperkalemia, and overall mortality. Despite recommendations to avoid using these two drugs concurrently, many healthcare providers continue to prescribe them together. We report a case of an elderly female with severe hyponatremia caused by trimethoprim-sulfamethoxazole superimposed on a chronic but stable mild hyponatremia.

RESUMO

Freedom of speech and expression is one of the core tenets of modern societies. It was deemed to be so fundamentally essential to early American life that it was inscribed as the First Amendment of the United States Constitution. Over the past century, the rise of modern life also marked the rise of the digital era and age of social media. Freedom of speech thus transitioned from print to electronic media. Access to such content is almost instantaneous and available to a vast audience. From social media to online rating websites, online defamation may cause irreparable damage to a physician's reputation and practice. It is especially relevant in these times of political turbulence where the battle to separate facts from misinformation has started a debate about the responsibility of social media. The historical context of libel and its applicability in the age of increasing online presence is important for physicians since they are also bound by duty to protect the privacy of their patients. The use of public rating sites and social media will continue to be important for physicians, as online presence and incidents of defamation impact the practice of medicine.

RESUMO

BACKGROUND: Squamous cell carcinoma of the nasopharynx, oropharynx and hypopharynx constitutes a majority of head neck malignancies. The incidence-based mortality across different races has been noted to be divergent. This study analyzes the trend in incidence-based mortality from the years 2000 to 2017 amongst both the genders in Caucasian/White and African American/Black patients. METHODS: The Surveillance, Epidemiology, and End Results (SEER) Database was queried to conduct a nation-wide analysis for the years 2000 to 2017. Incidence-based mortality for all stages of nasopharyngeal, oropharyngeal and hypopharyngeal cancer was queried and the results were grouped by race (Caucasian/White, African American/Black, American Indian/Alaskan native and Asian/Pacific Islander) and gender. All stages and ages were included in the analysis. t-test was used to determine statistically significant differences between various subgroups. Linearized trend lines were used to visualize the mortality trends of all sub groups. RESULTS: Across all races, the male to female gender disparity in mortality was ~1:3 in patients with nasopharynx and became worse to ~1:4 and ~1:5 for patients with oropharyngeal and hypopharyngeal cancers, respectively. Notably, the highest incidence-based mortality for nasopharyngeal cancers is seen in Asian/pacific Islander males and a similar peak is noted for hypopharyngeal cancers in African American/Black males. Incidence-based mortality rates (per 1000) for nasopharyngeal, oropharyngeal and hypopharyngeal cancer of all races and both the genders was noted to be divergent. CONCLUSION: A significant gender disparity exists in all three pharyngeal cancers across all races. It is unclear if female gender is protective but further study is warranted in a stage-specific and age-specific manner to better understand this disparity.

RESUMO

BACKGROUND: Squamous cell carcinoma is the most common subtype of malignancy found in patients with head and neck malignancy. There are other rare subtypes which are not adequately reported in medical literature. Lymphoepithelial carcinoma consists of lymphocytic infiltration in a background of undifferentiated carcinoma. They are most often seen in salivary glands but can also be found in other structures of the head and neck region. This analysis reports the nation-wide mortality of patients diagnosed with lymphoepithelial carcinoma of the head and neck. METHODS: Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) Database from the years 2000 to 2014. Incidence-based mortality for all stages was queried and results were grouped by gender and race (Caucasian/White, African American/Black, American Indian/Alaskan native and Asian/Pacific Islander). Paired T-test was used to determine statistically significance difference between various subgroups. RESULTS: Incidence-based mortality has been improving for African American/Black patients and has been worsening for Caucasian/White, American Indian/Alaskan native and Asian/Pacific Islander for the period of 2000 to 2014. The differences in mortality trends were statistically different (P < 0.05). The highest mortality rate per 1000 patients was seen in Asian/Pacific Islander population, followed by African American/Black, American Indian/Alaskan native and the least mortality was noted in Caucasian/White patients. When a similar analysis with linearized trend lines on gender was conducted, only African American/Black males and Asian/Pacific Islander females showed an improving trend in mortality. The sample size was a major limitation of this study (Caucasian/White - 134, African American/Black - 30, American Indian/Alaskan native - 5 and Asian/Pacific Islander - 87). CONCLUSION: Lymphoepithelial carcinoma is a rare subtype of head and neck malignancies whose incidence-based mortality showed a worsening trend. This study showed significant race and gender disparity amongst patients with lymphoepithelial carcinoma. Due to its rarity, this subtype warrants further study, especially with regards to its etiology, clinical course and cure rates.

RESUMO

Cancer stem cells (CSCs) are a unique population of cells found within tumors that are able to self-renew, restore the original heterogeneity of a tumor following treatment, and show increased tumorigenic potential when compared to other cancer cells. It is thought that they are responsible for the recurrence of tumors as well as the resistance to treatment that is seen clinically. CSCs are known to be involved in head and neck cancer (HNCs) specifically, as evidence for their existence can be found in head and neck squamous cell carcinoma (HNSCC), mucoepidermoid carcinoma (MEC), and adenoid cystic carcinoma (ACC), among others. Here, findings from various approaches to identifying and targeting CSCs and their downstream effectors in HNC are summarized, with an emphasis on recent advancements. Prognostic and therapeutic markers are discussed for each specific type of HNC, and novel treatment strategies and current clinical trials involving CSCs are detailed as well. The information provided here is intended to further the research on this important topic and lead to clinical impact in the battle against HNC.

RESUMO

BACKGROUND: Ocular and orbit melanoma is a rare subtype of melanoma for which outcomes have not been adequately reported. We have analyzed the incidence-based mortality trends of ocular and orbit melanoma over 15 years in USA. Most ocular melanomas originate from the uvea and, to a lesser extent, from the conjunctiva. Primary orbital melanoma is exceedingly rare. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was queried to find the incidence-based mortality for all patients diagnosed with ocular and orbit melanoma for the years 2000 to 2018. Results were grouped by gender and race (Caucasian/White, African American/Black, American Indian/Alaskan Native, and Asian/Pacific Islanders). A paired t-test was used to determine the statistically significant difference between various subgroups (p < 0.05). RESULTS: Incidence-based mortality has been the highest in Caucasian/White patients from 2000 to 2018, followed by African American/Black and Asian/Pacific Islander patients. American Indian/Alaskan native patients appear to have the least mortality. There was a statistically significant difference (p<0.05) in mortality between Caucasian/White patients from 2000 to 2018, and African American/Black and Asian/Pacific Islander patients. The sample size for African American/Black and American Indian/Alaskan native patients was too low to discern a meaningful trend in mortality. Overall, it appears that Caucasian males and females have a far higher and worsening incidence-based mortality compared to other races. CONCLUSION: Ocular melanoma and orbit melanoma are rare entities that are predominantly seen in Caucasian/White patients. This study shows that incidence-based mortality has been worsening for these patients in the past two decades. These entities have a poor prognosis and have not been studied extensively in immunotherapy trials. There is a need for new clinical trials to help improve mortality rates.

RESUMO

Cancer patients are at an increased risk of developing infections that are primarily treatment-driven but may also be malignancy-driven. While cancer treatments such as chemotherapy, radiotherapy, and surgery have been known to improve malignancy morbidity and mortality, they also have the potential to weaken immune defenses and induce periods of severe cytopenia. These adverse effects pave the way for opportunistic infections to complicate a hospitalized cancer patient's clinical course. Understanding the risk each patient inherently has for developing a bacterial, fungal, or viral infection is critical to choosing the correct prophylactic treatment in conjunction with their scheduled cancer therapy. This review discusses the most common types of infections found in hospitalized cancer patients as well as the current guidelines for prophylactic and antimicrobial treatment in cancer patients. In addition, it describes the interaction between antibiotics and cancer therapies for consideration when treating infection in a cancer patient.

RESUMO

BACKGROUND: Patients with melanoma frequently develop central nervous system metastases. Oligometastatic disease is often treated either by surgical resection or by stereotactic radiotherapy. This study investigates the trends and clinical outcomes of patients with melanoma who have undergone surgical procedures on the central nervous system during their hospitalization. METHODS: A retrospective study was performed based on admissions of adult patients who underwent craniotomy for metastatic melanoma from 2000 to 2014 using the Nationwide Inpatient Sample database. The primary outcome measure was all-cause in-hospital mortality. Secondary outcomes included hospital length of stay (LOS) and discharge disposition (home/home with health care and skilled nursing facilities/long-term acute care (SNFs/LTAC)). Factors associated with in-hospital mortality were examined by multivariable logistic regression. We adjusted for patient and hospital characteristics, payer, and comorbid conditions. We also examined trends of mortality for the study years. RESULTS: There were an estimated 1,216 discharges of patients with melanoma undergoing craniotomy during the study period. Patients undergoing surgical interventions were typically males (69%) and whites (79%). Ninety-eight percent of procedures were performed at teaching hospitals. Unadjusted all-cause in-hospital mortality was 3.1%. There was no significant difference in mortality over 13 years. Age, gender, and race were not associated with increased in-hospital mortality. LOS was longer in elderly and those with higher Charlson Comorbidity Index. Of the survivors, 76% were discharged to home or with home healthcare while 24% were discharged to SNFs/LTAC. Patients with age > 65 (odds ratio (OR): 2.9; 95% confidence interval (CI): 2.2 - 3.9, P < 0.001) and those with higher Charlson Comorbidity Index (OR: 1.2; 95% CI: 1.1 - 1.3) had higher odds for being discharged to SNFs/LTAC. CONCLUSIONS: Patients who undergo craniotomy for metastatic melanoma have a low in-hospital mortality rate. One quarter of patients were discharged to SNFs/LTAC.

RESUMO

Clinical endpoints are essential for assessing the safety and efficacy of new cancer therapies. They are used by oncologists to help guide clinical decision making. While overall survival (OS) has frequently been regarded as the "gold standard" primary clinical endpoint, it's utility is constrained by several disadvantages. The time-consuming nature of trials using OS has led to a recent push to explore surrogate clinical endpoints and their potential to serve as primary clinical endpoints in lieu of OS. Additionally, it is becoming evident that other endpoints add valuable information about quality of life and treatment failure as their use is becoming increasingly prevalent in oncology clinical trials. Without a doubt, the use of clinical endpoints will continue to expand and evolve as new cancer therapies are developed and novel treatments, including immunotherapy, draw interest. This review explores the roles of primary and surrogate clinical endpoints as well as the benefits and drawbacks of each specific endpoint. In addition, it directly compares the unique features of each suggesting some of the specific uses each one fulfills.

RESUMO

Patient data have conventionally been thought to be well protected by the privacy laws outlined in the United States. The increasing interest of for-profit companies in acquiring the databases of large health care systems poses new challenges to the protection of patients' privacy. It also raises ethical concerns of sharing patient data with entities that may exploit it for commercial interests and even target vulnerable populations. Recognizing that every breach in the confidentiality of large databases exposes millions of patients to the potential of being exploited is important in framing new rules for governing the sharing of patient data. Similarly, the ethical aspects of data voluntarily and altruistically provided by patients for research, which may be exploited for commercial interests due to patient data sharing between health care entities and third-party companies, need to be addressed. The rise of technologies such as artificial intelligence and the availability of personal data gleaned by data vendor companies place American patients at risk of being exploited both intentionally and inadvertently because of the sharing of their data by their health care provider institutions and third-party entities.

RESUMO

Hepatotoxicity of chemotherapeutic agents such as methotrexate, oxaliplatin, and irinotecan have been well documented and characterized allowing for careful management by oncologists during administration. However, the rapid advance of the field of oncology and introduction of new classes of therapies such as small molecule inhibitors and immunotherapies have introduced new hepatotoxicity challenges and management strategies. This work is a compilation of the hepatotoxicity and recommended management of various chemotherapies and targeted agents, with a focus on the newer classes of targeted anticancer agents.

RESUMO

The study of genetic polymorphisms has significantly advanced the field of personalized medicine. Polymorphism of genes influence the efficacy of drugs used for treating medical conditions such as depression, cardiac diseases, thromboembolic disorders, oncological diseases, etc. The study of genetic polymorphism is beneficial for drug safety as well as for assessing therapeutic outcomes. Understanding and detecting genetic polymorphisms early on in patients can be useful in selecting the correct chemotherapeutic agent and appropriate dosage for a patient. Knowing the genetic profile of a patient and the interindividual response to various drugs significantly influences the proper selection of medication - a key step towards personalized medicine. Polymorphisms also make patients susceptible to certain cancers and identification of these polymorphisms early can be useful for a personalized treatment plan. The Genome-Wide Association Studies (GWAS) project where millions of genetic variants in the genomes of many individuals are studied to identify connections between what is present on the gene and the phenotype of the patient has enhanced the prospect of personalized medicine. GWAS has been used to identify hundreds of diseases associated to genetic polymorphisms. Individual pharmacokinetic profiles of patients to drugs enable the development of early surveillance protocols to prophylactically prevent patients from having adverse reactions. Furthermore, patient-derived cellular organoids are another advancement that allows researchers to screen for polymorphisms of the patient for adverse reactions from chemotherapy and will allow for the development of new medications that are specific to the profile of the patient's tumor. These advances have led to significant progress towards personalized medicine. The functional consequences of genetic polymorphism on cancer drugs and treatment are studied here.
