The Rat Sarcoma virus (RAS) gene family is characterized by three genes (KRAS, NRAS and HRAS) encoding for closely related GTPase proteins responsible for the signal transduction within the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3 kinase (PI3K) pathways. KRAS mutations are the most important and frequent alterations in this family, accounting for 85% of RAS mutations observed in the oncologic population.

1. Introduction

The Rat Sarcoma virus (RAS) gene family is characterized by three genes (KRAS, NRAS and HRAS) encoding for closely related GTPase proteins responsible for the signal transduction within the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3 kinase (PI3K) pathways. This group of genes is associated with the control of cell growth, survival and differentiation [1][2], and it is characterized by the most frequently observed genomic alterations in human cancers, being detected in approximately 19% of tumors [3][4].
KRAS mutations are the most important and frequent alterations in this family, accounting for 85% of RAS mutations observed in the oncologic population [5]. More specifically, KRAS exon 2, exon 3 and exon 4 mutations are present in 13.98%, 1.17% and 0.62% of all cancer types [2][6], respectively, especially in pancreatic ductal adenocarcinoma (PDAC) (88% of patients), in colorectal cancer (CRC) (45–50% of cases) and in lung adenocarcinoma (AC) (30–35% of patients) (Table 1) [5][6][7][8].

2. KRAS Mutations in Lung Cancer

The protein encoded by KRAS is a GTPase regulated by tyrosine kinase receptors that in turn activate the RAF/MEK/MAPK and PI3K/AKT signaling pathways, leading to a strong promotion of cell growth and replication that determines cell survival. The presence of mutations in KRAS blocks this protein in the active GTP-bound conformation, thereby activating constitutively downstream signaling pathways, finally resulting in uncontrolled cell growth [9]. Specifically, this continuous activation confers to cancer cells the ability to grow in lower glucose concentrations than those required for the growth of normal cells or cancer cells that do not have KRAS mutations [10][11]. As for other cancer types, KRAS mutations in lung cancers typically occur in hot-spot codons of exons 2, 3 and 4.

2.1. KRAS Mutations in NSCLC

In general, lung cancer has a complex and heterogeneous background. Indeed, it can be histologically subdivided into non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), accounting for 85% and 15% of all lung neoplasia, respectively [12]. NSCLCs are further subdivided into three histologic types: AC, squamous-cell carcinoma (SCC) and large-cell carcinoma (LCC), which represent 40%, 25–30% and 5–10% of all lung cancers, respectively [8]. The occurrence of KRAS mutations differs based on the specific lung cancer type/subtype, being higher in NSCLC than in SCLC, and within NSCLC, KRAS mutations are more frequent in lung AC than SCC (Table 2). Interestingly, a recent study established two different groups of KRAS-mutant NSCLC, KRAS-dependent and KRAS-independent according to their requirement for KRAS mutations to maintain oncogenicity. However, to date, these data are preliminary and need to be confirmed in larger cohorts [9].

NSCLC 25–30% 34% 1.89% 0.24%

SCC 3–4% 7% <3% <0.5%
AC: AdenoCarcinoma; NSCLC: Non-Small Cell Lung Cancer; SCC: Squamous-Cell Carcinoma (AACR Project GENIE Consortium, 2017 [7]).

2.1.1. KRAS Mutations in Lung Adenocarcinoma

In the AC subtype, almost 30–35% of cases are driven by a KRAS mutation [5][6][7][8], mainly in exon 2, with the c.34G > T (p.G12C) change being the most prevalent (Table 3) [13].

3. KRAS Mutations in Population-Based Cohorts of Lung Adenocarcinomas

The frequency of KRAS mutation in patients affected by lung AC differs among ethnicities and countries of origin, being higher in Caucasian (where they are detected in up to 30% of patients) than in Asians or in Africans (occurring in 16% and 9% of cases, respectively) [14][15][16][17][18][19][20].

3.1. KRAS Mutations in Caucasians Affected by Lung AC

In Europe, the most frequent KRAS mutations in lung AC are found in exon 2, with a general mutational rate close to 30% [14][15][16]. Differences can also be observed among European countries (28% in Germany, 29–31% in France, 27% in Italy, 19–27% in Greece and 43.3% in Spain) [14][15][16][21][22][23][24] and even among regions of the same country: for example, the island of Sardinia in Italy has the lowest frequency among all Italian regions [25]. This difference could be due to the physical separation of the island from the country, reflecting different lifestyle or environmental behaviors.
In Europe, 86% of mutations in exon 2 are located in codon 12, with the c.34G > T (p.G12C) mutation being the most common one (observed in 34% of cases) [14] (Table 4).

3.2. KRAS Mutations in Asians Affected by Lung AC

Several studies show that Asian populations have significant lower KRAS mutation incidence than that in the Caucasian and Afro-American populations [33][34]. As for Europe, even in Asia there is a wide range in the mutation frequencies among countries, with the highest values in Vietnam (21%, close to European populations) and the lowest in China (8.4–13%), Japan (10%) and Indonesia (7%) [28][35][36][37][38]. As usual, the most affected region is KRAS exon 2, but the most common KRAS exon 2 mutational subtype is the c.35G > A (p.G12D) change, with a rate of 25.5%, followed by c.34G > T (p.G12C) (24.5%) [17][27][39] (Table 4).
The frequency and type of mutations in exons 3 and 4 in Asian populations mirror those observed in European countries [39] (Table 4).

3.3. KRAS Mutations in Africans Affected by Lung AC

Central and West Africa are the regions with the lowest incidence rates of lung cancer for both sexes (0.8%) worldwide [40], while in North Africa, the KRAS mutations is observed in 6–9% of patients [26][31][41]. Specific studies concerning molecular characterization in African populations are extremely rare, and the data are sporadic. In Morocco, the c.34G > T (p.G12C) change is the most prevalent one (detected in 73% of KRAS-mutant cases) [26], while in Tunisia, c.38G > A (p.G13D) followed by c.35G > A (p.G12D) are predominant (42.8% and 28.5% of cases, respectively) [31] (Table 4). However, the size cohort is often too small to derive any conclusion.

3.4. KRAS Mutations in the Heterogeneous Lung AC American Population

In the USA, KRAS mutations are observed in a significantly high proportion of cases, up to 47.5% of patients, especially in exon 2 (90.6%), with the c.34G > T (p.G12C) change being the most prevalent one (41.2%) [29]. Focusing on the different ethnicities, the prevalence of KRAS mutations in African-American patients was less than that observed in the Caucasian group (17% versus 26%) [42]. Interestingly, American Hispanic patients have better survival than non-Hispanic/non-African cases, despite the fact that this population is diagnosed for cancer at a later stage due to social factors. This situation, defined also as the “Hispanic paradox”, has suggested investigating Hispanic individuals’ biological, pathological and molecular factors [30]. First, researchers observed a lower frequency of KRAS mutations compared with the Caucasian population (15.7% and 20–35% respectively) [30], and, second, researchers described that Hispanics have more KRAS changes in exon 2 codon 13 and in exon 3 codon 59 than non-Hispanics [43], possibly explaining the inferior cancer aggressiveness.
In Latin America, the frequency of NSCLC (in particular lung AC) with KRAS mutations corresponds to 14% [44], with little differences, ranging from 12.9% in Colombia to 15.9% in Mexico and 16.8% in Peru [44].
Two relevant observations come from analyses of Puerto Rican and Brazilian cohorts [45][46]. In Puerto Rico, lung ACs present with KRAS mutations in 18.7% of the cases, a rate that is significantly higher than in the aforementioned general Hispanic populations [44][46]; in Brazil, 14.6% of lung ACs harbour KRAS mutations, with a higher prevalence in non-Asian patients [45]: in both populations, c.34G > T (p.G12C) is the most diffused type of alteration.
